ROBERT M. CLAYTON III, Presiding Judge
S.B.A. (“Appellant”) appeals the judgment of the juvenile division of the Circuit Court of St. Charles County (“the trial court”) finding he had committed two delinquent acts that would have constituted two counts of third-degree assault in violation of section 565.070.1(1) RSMo 20001 if they were committed by ah adult. We affirm.
I. BACKGROUND
In this case, the Juvenile Officer’s2 allegations leading to the findings of delinquency set out above were based on accomplice liability. Specifically, the Juvenile Officer’s first amended petition alleged that on or about January 13, 2016, (1) Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to K.M. by striking him with a closed fist, causing K.M. to sustain an injury to his nosé,” and (2) Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to A.H. by striking him in the face” (collectively “the two allegations in the Juvenile Officer’s petition”).
An adjudication hearing took place-with respect to the two allegations in the Juvenile Officer’s petition on July 5, 2016.3 At the hearing, Appellant made oral motions for judgment of acquittal at the close of the Juvenile Officer’s evidencé and at the close of all of the evidence, which the trial court denied! On July 5, the trial ’court entered an order and judgment of jurisdiction, which found that based upon the evidence presented at the adjudication hearing, the two allegations in the- Juvenile Officer’s petition were true beyond a reasonable doubt. Consequently, the trial court’s decision also found Appellant had committed two delinquent acts that would have constituted two counts of third-degree assault in violation of section 565.070.1(1) if they were committed by an adult; the trial court assumed jurisdiction over Appellant; and the trial court placed Appellant in the continued custody of his mother pending a dispositional hearing,
The trial court held the dispositional hearing on July 18, and the trial court entered an order and judgment of disposition regarding delinquency, finding continued jurisdiction of Appellant and placing him in the continued custody of his mother subject to court supervision. The rules of court supervision were attached to the trial court’s decision.and were set out-in an agreement signed by Appellant, his mother, and a representative of the Juvenile Officer.
On July 21, Appellant filed notice of. appeal with this Court; Subsequently, on April 3, 2017, the trial court entered an order terminating its jurisdiction over Appellant, finding he had successfully completed all aspects of court supervision and was no longer in need of the care and protection of the court. The submission of this appeal followed.'
II. DISCUSSION
Appellant raises two points on appeal, both of which assert there was insufficient evidence to support the trial court’s findings that he committed delinquent acts of third-degree assault. In response, the Juvenile Officer filed , a motion to dismiss Appellant’s appeal on the ‘grounds it is moot; that motion has been taken with the case. Because the issue of whether an appeal is moot is a threshold question of appellate review, we will consider the Juvenile Officer’s motion to dismiss before examining the merits of Appellant’s claims on appeal. See Broyles v. Department of Community Health & Environment of St. Charles County, 456 S.W.3d 517, 520 (Mo. App. E.D. 2015) (“[a] threshold question in any appellate review of a controversy is the mootneSs of the controversy”).
A. Whether Appellant’s Appeal is Moot
An appeal of a trial court’s judgment is considered to be moot if the judgment rendered has no practical effect on an existing controversy, i.e., an existing controversy is not susceptible to some relief. Id. Accordingly, “[w]hen something occurs, that makes a decision on appeal unnecessary or makes it impossible for the appellate court to grant effective relief,, the appeal is moot and generally should be dismissed.” Id. Nevertheless, an appellate court may exercise its discretion to decide an otherwise moot appeal under three circumstances, (1) where the case becomes moot after it is argued and submitted; (2) where the issue raised in the case is one of general public interest and importance, is likely to recur, and will otherwise evade appellate review; or (3) “if the decision could have significant collateral consequences for one or more of the parties.”4, 5 M.T. v. Juvenile Officer, 431 S.W.3d 539, 542-43 (Mo. App. E.D. 2014); see In re A.G.R., 359 S.W.3d 103, 108 (Mo. App. W.D. 2011) (an appellate court has discretion to decide an otherwise moot appeal when one of the exceptions to the mootness doctrine applies).
In the Juvenile Officer’s motion to dismiss, he argues Appellant’s appeal should be dismissed as moot because the trial court’s April 3, 2017 order terminated its jurisdiction over S.B.A. and therefore, there is no longer an existing controversy susceptible to some relief. The Juvenile Officer further contends this Court does not have discretion to decide Appellant’s appeal because none of the three exceptions to the mootness doctrine apply to this ease.
In his suggestions in opposition to the Juvenile Officer’s motion to dismiss, Appellant asserts that, inter alia, the third exception to the mootness doctrine applies to this case. Specifically, Appellant argues the trial court’s judgment could have significant collateral consequences for Appellant because there is a movement to make more juvenile records public. In support of his argument, Appellant cites to In Interest of N.R.W., 482 S.W.3d 473 (Mo. App. E.D. 2016) and T.S.G. v. Juvenile Officer, 322 S.W.3d 145 (Mo. App. W.D. 2010). In N.R.W. and T.S.G., like in the instant case, the appellate court considered whether a juvenile’s appeal of an adjudication was moot under circumstances where the trial court no longer had jurisdiction over the juvenile as of the time of the appeal. See 482 S.W.3d at 475-76; 322 S.W.3d at 147-48; see also State v. Thomas, 70 S.W.3d 496, 504-05 (Mo. App. E.D. 2002) and section 211.041 RSMo Supp. 2009 and section 219.021.1 RSMo Supp. 2016 (indicating the trial court, in;N.R.W. no longer had juris diction over the juvenile because he was over eighteen years old and had been previously committed to the division of youth services).
In N.R.W., the juvenile was adjudicated delinquent for an offense that would have been considered a felony if it -was committed by an adult. 482 S.W.3d. at 475. In considering whether to decide the juvenile’s appeal on the merits or dismiss it as moot, our Court found section 211.321.2(2) provides that the records of the juvenile’s dispositional hearing on a “felony offense” are public information to the same extent as records in criminal proceedings, and such evidence could be introduced during the sentencing phase if the juvenile were later tried for an offense as an adult. See N.R.W., 482 S.W.3d at 475, 475 n.1 (citing, inter alia, section 211.321.2(2) and State v. Sapien, 337 S.W.3d 72, 77-78 (Mo. App. W.D. 2011)); see also 211.321.2(2) RSMo Supp. 2005. Accordingly, this Court held the adjudication could have significant collateral consequences for the juvenile into his adult life, and therefore, the third exception to the mootness doctrine applied. N.R.W., 482 S.W.3d at 475. Further, we did not dismiss the juvenile’s appeal but instead considered the merits of the juvenile’s claims. Id. at 475-79.
In T.S.G., the juvenile was adjudicated delinquent for a “status offense” of behavior injurious to the juvenile’s welfare6 after the court amended the juvenile’s officer petition at the close of the evidence. 322 S.W.3d at 147-48. In determining whether to decide the juvenile’s appeal on the merits or dismiss it as moot, the Western District considered the juvenile’s arguments that the third exception to the mootness doctrine applied to her status offense. Id. at 148. The juvenile argued the exception applied because the original offense she was charged with was sexual in nature, and therefore, it was possible the juvenile could later be subject to sex offender registration due to “the rapidly changing statutes in Missouri dealing with this area of law[J” Id. The juvenile also argued the third exception to the mootness doctrine applied because of the existence of “the movement to make more juvenile records public[.]” Id. In addition, the T.S.G. Court also considered the juvenile officer’s concession on appeal that the adjudication could have significant collateral consequences for the juvenile in the future. Id. Under those circumstances, the Western District implicitly found the third exception to the mootness doctrine applied, and the Court did not dismiss the juvenile’s appeal but instead considered the merits of the juvenile’s claims. Id. at 147-50.
We acknowledge the instant case is distinguishable from N.R.W. and T.S.G. because Appellant was adjudicated delinquent for offenses that would be considered misdemeanors if they were committed by an adult7 instead of the “felony offense” at issue in N.R.W. or the “status offense” and original charge that was sexual in nature at issue in T.S.G. See 482 S.W.3d at 475; 322 S.W.3d at 147-48. In addition, unlike in T.S.G., there is no concession by the Juvenile Officer in this case that Appellant’s adjudication could have significant collateral consequences for him in the future. See 322 S.W.3d at 148. Nevertheless, we find N.R.W. and T.S.G. are instructive to our ultimate determination that the third exception to the mootness doctrine applies to this case.
First, we agree with Appellant’s contention that, as the juvenile argued in T.S.G., there is a movement to make more juvenile records public. See 322 S.W.3d at 148; see generally State v. Prince, No. ED102938, — S.W.3d -, -, 2017 WL 2644431 at *1, 8 (Mo. App. E.D. June 20, 2017) (the State argued on appeal that the trial court did not err in admitting records of the defendant’s juvenile adjudication at trial because the records fell within the scope of a Missouri constitutional provision allowing for the admission of some evidence of prior criminal acts); see also State ex rel. Hawley v. Heagney, 523 S.W.3d 447, 450 (Mo. banc 2017) (“in deciding whether a case is moot, an appellate court is allowed to consider matters outside the record”) (quotations omitted). Furthermore, it is foreseeable that the movement to make more juvenile records public could result in, (1) records of a juvenile’s dispositional hearing on an offense other than one categorized as a “felony” to be considered public information to the same extent as records in criminal proceedings; (2) such evidence to possibly be introduced during the sentencing phase if the juvenile were later tried for an offense as an adult; and (3) an individual having other lifelong consequences and stigma related to his juvenile adjudication. See id.; see also N.R.W., 482 S.W.3d at 475; section 211.321,2(2).
Under these circumstances, and similar to our Court’s holding in N.R.W., we find Appellant’s adjudication could have significant collateral consequences for Appellant into his adult life, and therefore, the third exception to the mootness doctrine applies. See 482 S.W.3d at 475; see also T.S.G., 322 S.W.3d at 148. To hold otherwise would possibly imply that the merits of a juvenile adjudication could not be reviewed on appeal simply because, over time, a juvenile has successfully completed all aspects of supervision ordered by the court or the individual has simply reached an. age where the court no longer has jurisdiction over him.8 It is this Court’s view that such a result would be unacceptable and minimize the value of an individual’s pursuit of justice and/or vindication in á court proceeding finding he, as a juvenile, committed an act that would have constituted the violation of a criminal statute if it was committed by an adult. Based on the foregoing, the Juvenile Officer’s motion to dismiss- is denied, and we exercise our Court’s discretion to consider the merits of Appellant’s claims- on appeal.9 See N.R.W., 482 S.W.3d at 475-79; T.S.G., 322 S.W.3d at 147-50.
B.. The Merits of Appellant’s Claims on Appeal
Appellant raises two points on appeal, Appellant’s first point alleges there was insufficient evidence he committed the delinquent act of third-degree assault against K.M. under a theory of accomplice liability, while Appellant’s second point on appeal contends there was insufficient evidence he committed the delinquent act of third-degree assault against A.H. under a theory of accomplice liability.
1. The Standard of Review
Our Court reviews an appeal of a juvenile adjudication under the same standard as any other court-tried case. In re D.M., 370 S.W.3d 917, 919, 922 (Mo. App. E.D. 2012) (superseded by constitutional amendment on other grounds)10; In re J.A.H., 293 S.W.3d 116, 119 (Mo. App. E.D. 2009). Accordingly, we will .affirm the trial court’s judgment unless it is not supported by substantial evidence, it is against the weight of the evidence, it erroneously declares the law, or it erroneously applies the law. Id.
In reviewing a challenge to the sufficiency of the evidence to support a juvenile adjudication, our Court’s role is to determine whether the juvenile officer has introduced sufficient evidence from which a reasonable person could have concluded the accused committed the delinquent act that would have constituted a violation of a criminal statute if it was committed by an adult. See In re T.B., 351 S.W.3d 243, 244 (Mo. App. E.D. 2011); J.A.H., 293 S.W.3d at 119, Furthermore, the juvenile officer has the burden of proving each element of the criminal offense beyond a reasonable doubt, and the juvenile officer may meet this burden by the presentation of circumstantial evidence alone. T.B., 351 S.W.3d at 245-46; J.A.H, 293 S.W.3d at 120.
In determining whether there is sufficient evidence to affirm a juvenile adjudication, “the trial court’s decision must be given the same deference as it would be given- in an adult criminal proceeding.” D.M., 370 S.W.3d at 922. Accordingly, we view the evidence and reasonable inferences therefrom in the light most favorable to the trial court’s judgment, and we disregard all contrary evidence and inferences. Id., T.B., 351 S.W.3d at 244; J.A.H., 293 S.W.3d at 119. In.addition, “[t]he credibility of witnesses and the weight to be given their testimony is a matter for the trial court, which is free to believe none, part, or all of their testimony,” and an appellate court defers to the trial court on such matters. K.A.R. v. Juvenile Officer, 412 S.W.3d 475, 483 (Mo. App. W.D. 2013) (quotations omitted); J.M.G. v. Juvenile Officer, 304 S.W.3d 193, 196 (Mo. App. W.D. 2009).
2. Appellant’s Alleged Delinquent Acts and the General Law Pertaining to Those Acts'
In this case, the two allegations in the Juvenile Officer’s petition alleged Appellant had committed delinquent acts that would have constituted two counts of third-degree assault 'in violation' of section 565.070.1(1) if they were committed by ah adult, and both allegations were based on accomplice liability. Specifically, the Juvenile Officer’s first amended petition alleged that on or about January 13, 2016, (1) Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to KM. by striking him with a closed fist, causing KM. to sustain an injury to his nose,” and (2) Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to A.H. by striking him in the face.”
Section 565.070 provides in relevant part that a person commits the class A misdemeanor of third-degree assault if, inter alia, he “recklessly causes physical injury to another person[.]” Section 565.070.1(1) and .2. “A person ‘acts recklessly’ .., when he consciously disregards á substantial and. unjustifiable risk that circumstances exist or that a result will follow, and such disregard constitutes a gross deviation from the standard of care which a reasonable person would exercise in the situation.” Section 562.016:4 (emphasis omitted).
“A person is deemed criminally responsible for the conduct of others when ‘with the purpose of promoting the commission of an offense, he aids or agrees to aid or. attempts to aid such other person in planning, committing or attempting to commit the offense.’ ” M.A.A. v. Juvenile Officer, 271 S.W.3d 625, 629 (Mo. App. W.D. 2008) (quoting, inter alia, section 562.041.1(2)). Pursuant to the concept of accomplice liability, all persons who act in concert to commit an offense are equally responsible for the act. Id.; State v. Myles, 479 S.W.3d 649, 660 (Mo. App. E.D. 2015). In addition, “[a] [person] who embarks upon a course of criminal conduct with others is responsible for those [offenses] which he could reasonably anticipate would be part of that conduct.” State v. Brewer, 476 S.W.3d 321, 324 (Mo. App. E.D. 2015).
To support an adjudication based on accomplice liability, the juvenile officer need only show that the accused associated himself with the venture or participated in the offense in some manner; there is no need to show the accused personally committed every element of the crime. Myles, 479 S.W.3d at 660; M.A.A., 271 S.W.3d at 629. Instead, any direct or circumstantial evidence demonstrating any form of affirmative participation in the offense is sufficient to support an adjudication. Id.; State v. Nance, 880 S.W.2d 578, 580 (Mo. App. E.D. 1994). In other words, “we must determine whether all the facts and circumstances in evidence considered together raise a reasonable inference [an accused] participated in the offense [in question].” State v. Townsend, 810 S.W.2d 726, 727 (Mo. App. E.D. 1991).
3. The Evidence Presented at Appellant’s Adjudication Hearing
The following was presented at Appellant’s adjudication hearing. On January 13, 2016, friends A.H., K.M., and D.S. were at A.H.’s residence. K.M. and D.S. were helping A.H. fix his front porch, and A.H. was using a hammer. Later that day when the three boys were inside of A.H.’s house, there was a knock on the door, and A.H. went outside. A.H. then saw Appellant, B.S. and'C.S., three boys A.H. knew from school, standing up the street, and B.S. said, “let’s fight, let’s fight.” A.H., KM., and D.S. then walked up the street to where Appellant, B.S., and C.S. were standing, and A.H. discarded the hammer.
C.S. then grabbed the hammer, and as KM. tried to take it from him, someone punched K.M. in the nose, breaking it. No one saw who punched K.M.
Subsequently, B.S. and A.H. began to punch each other, C.S. hit.A.H. once,- and Appellant hit A.H. a couple of times. As a result of the fight, A.H. had a black eye, swollen lip, three bumps on his head, scratches, pain, problems with his memory, and problems sleeping.
A neighbor witnessed the fight between the two groups of boys. When he called 911, Appellant, B.S., and C.S. fled the scene together.
In addition, a little over a month after the incident, Officer David Fruits with the St. Charles City Police Department spoke with Appellant about the fight on the front porch of Appellant’s residence. During their conversation, Appellant told Officer Fruits he did not remember being involved in the fight.
4. Whether there was Sufficient Evidence Appellant Committed the Delinquent Act of Third-Degree Assault Against K.M.
We now turn to Appellant’s first point on appeal, in which he contends there was insufficient evidence he committed the delinquent act of third-degree assault against K.M. under a theory of accomplice liability. With respect to this delinquent act, the trial court found, based upon the evidence adduced at the adjudication hearing, it was true beyond a reasonable doubt that Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to K.M. by striking him with a closed fist, causing K.M. to sustain an injury to his nose.”
Appellant argues the Juvenile Officer failed to prove he affirmatively participated in the assault against K.M., because there was no evidence Appellant was the individual who punched K.M. and there was no evidence Appellant knew K.M. was going to be at A.H.’s house prior to the fight or at the fight itself. We disagree.
As indicated above, because this case involves an adjudication based on accomplice liability, it was not necessary for the Juvenile Officer to show Appellant personally committed every element of third-degree assault. Myles, 479 S.W.3d at 660; M.A.A., 271 S.W.3d at 629. In addition, it was not necessary for the Juvenile Officer to show that before the fight, Appellant intended to commit the offense against K.M. specifically. See Brewer, 476 S.W.3d at 324. Instead, the Juvenile Officer only needed to demonstrate that Appellant associated himself with the venture or participated in the offense in some manner, and any circumstantial evidence demonstrating any form of affirmative participation in the offense was sufficient to support Appellant’s adjudication. Myles, 479 S.W.3d at 660; M.A.A., 271 S.W.3d at 629; Nance, 880 S.W.2d at 580.
An accused’s affirmative participation in an offense may be reasonably inferred from: his presence at the scene of the offense; his association with others involved before, during, and after the offense; his conduct before the - offense; his conduct during the offense, including making no effort to assist the victims; and his conduct after the offense, including fleeing from the scene and failing to talk to the police relatively soon after the incident. State v. Davison, 601 S.W.2d 623, 628 (Mo. 1980); State v. Kobel, 927 S.W.2d 455, 459 (Mo. App. W.D. 1996); Nance, 880 S.W.2d at 580; Townsend, 810 S.W.2d at 727. While none of the preceding factors alone is sufficient to uphold an adjudication, Missouri Courts have considered the presence of multiple factors to be sufficient evidence of an accused’s affirmative participation in an offense. See id.
Viewing the evidence in this case and all reasonable inferences therefrom in the light most favorable to the trial court’s judgment, we find there was sufficient evidence of Appellant’s affirmative participation in the assault against K.M. Importantly, Appellant was not merely present at the scene of the offense against KM. Rather, Appellant was directly involved in the fight between the two groups of boys, hitting A.H. a couple of times. By being involved in the fight against A.H., K.M., and D.S., Appellant could reasonably anticipate K.M. would be punched and injured as a result of the fight. See Brewer, 476 S.W.3d at 324 (“[a] [person] who embarks upon a course of criminal conduct with others is responsible for those crimes which he could reasonably anticipate would be part of that conduct”).
In addition, Appellant' continually associated himself with B.S. and C.S. before the offense: when the three boys knocked on the door of A.H.’s house; when B.S. then told A.H., “let’s fight, let’s fight”; and when A.H., K.M., and D.S. then approached Appellant, B.S., and C.S. Appellant also continually associated . himself with B.S. and C.S. during-and after the time K.M. was punched in the nose and injured. Finally, during and immediately after the assault against K.M., Appellant made no effort to assist K.M.; instead, Appellant fled from the scene, with B.S. and C.S..and did not talk to the police until over a month after the incident.
Because a reasonable person could have concluded from all of the preceding facts and circumstances that Appellant affirmatively participated in the assault against K.M., Appellant’s first point on appeal is denied.11 See Davison, 601 S.W.2d at 628; Myles, 479 S.W.3d at 660; T.B., 351 S.W.3d at 244; J.A.H., 293 S.W.3d at 119; M.A.A., 271 S.W.3d at 629; Kobel, 927 S.W.2d at 459; Nance, 880 S.W.2d at 580; Townsend, 810 S.W.2d at 727.
5, Whether there was Sufficient Evidence Appellant Committed the Delinquent Act of Third-Degree Assault Against A.H.
In Appellant’s second and Anal point on appeal, he contends- there was insufficient evidence he committed the delinquent act of third-degree assault against A.H. under a theory of accomplice liability. With respect to this delinquent act, the trial court found, based upon the evidence adduced at the adjudication hearing, it was true beyond a reasonable doubt that Appellant, “acting in concert with two other juveniles, recklessly caused physical injury to A.H. by striking him in the face.”
In this point on appeal, Appellant does not dispute the Juvenile Officer presented sufficient evidence that he affirmatively participated in the assault against A.H. Instead, Appellant only contends there was insufficient evidence to support the trial court’s finding he committed the delinquent act of third-degree assault against A.H. because there was evidence A.H. “consented” to the infliction of physical injury by implicitly agreeing to fight Appellant. Appellant further maintains consent was an available defense for Appellant pursuant to section 565.080.1(1).
Section 665.080,1 states in relevant part: “When conduct is charged to constitute an offense because it causes or threatens physical injury, consent to that conduct or to the infliction of the injury is a defense only if [inter alia]. (1) The physical injury consented to or threatened by the conduct is not serious physical injury[.]” Additionally, section 565.080.2 provides, “[t]he,defendant shall have the burden of injecting the issue of consent.” In order to meet his burden of injecting the issue of consent, an accused must raise the issue to the trial court and must produce evidence of consent. See State v. Churchill, 454 S.W.3d 328, 331, 341 (Mo. banc 2015) (finding a defendant did not meet her burden of injecting the issue of retraction in a court? tried perjury case where she did not raise the issue to the trial court but instead raised the claim for the first, time on appeal); State v. Latall, 271 S.W.3d 561, 563-65 (Mo. banc 2008) (finding a defendant met his burden of injecting the issue of good cause when he produced evidence of the issue, i.e.,‘when the issue was supported by. the evidence); see also section 556.051(1).
In this case, Appellant concédes' that “arguably, the [trier of fact] might have found that [A.H.] suffered serious physical injury” and “[e]onsent is .not a defense [under section 565.080.1(1)] when, the physical injury consented to is,, serious physical injury,” Nonetheless, Appellant claims consent was still an available .defense because the court did not' find serious physical injury occurred and the court was not asked to make that determination since the Juvenile Officer’s petition did not allege Appellant’s conduct caused A.H, serious physical injury. For purposes of this appeal only, we assume that despite Appellant’s concessions, it was possible for consent-.to be an available defense in this case.12 - .
Nevertheless, based on the record before "us in this case, Appellant did not raise the issue of consent to the trial court, either before, during, or after his court-tried-hearing. The transcript of the-adjudication hearing reflects Appellant raised a sufficieney-of-the-evidence claim during oral motions for judgment of acquittal, arguing he should not be found guilty of the delinquent act against A.H. only because, (1) there was insufficient evidence Appellant was involved in the fight because there .were many inconsistencies in the testimony presented at. the hearing and there was no physical identification of Appellant; and (2) Appellant acted in self-defense or in defense of others. The issue of consent was also not raised by Appellant in any other portion of the record on appeal.13
In sum, the issue of consent was not a part of Appellant’s trial strategy, the issue was not raised' to’ the trial court' in any manner such as making the trial court aware of section 565.080 or the portion of the Notes on Use to MAI-CR 3d 319.16 discussing the defense,14 and the issue is being raised for the first time on appeal. Under these circumstances, we find Appellant did not meet his burden of injecting the issue of consent pursuant to section 565.080.2, and the trial court did not err in failing to apply a defense that was not brought to its attention. Point two is denied. See Churchill, 454 S.W.3d at 341 (denying an appellant-defendant’s point under similar circumstances).
III. CONCLUSION
The trial court’s judgment is affirmed.
