JUSTICE HARRIS delivered the opinion of the Court.

MEMORANDUM OPINION

Derek Joseph Daigneault was convicted of the murder of his cousin, Mandy Rose Reynolds, and sentenced to life in prison. We affirm the trial court’s judgment. BACKGROUND Mandy’s body was found burning in a residential development area in Robinson, Texas, in April of 2023. Daigneault quickly became a suspect. He called Robinson police on Mandy’s cell phone—impersonating Mandy, was seen

buying and loading into Mandy’s car a container like the one found at the scene in which Mandy was burned, fled to Kansas and led Kansas police on a high speed chase in Mandy’s car, had Mandy’s handgun in his possession in the car, crashed the car, fled on foot, and was caught hiding in a grocery store.

In two issues, Daigneault contends the evidence is insufficient to support his conviction and the trial court abused its discretion in excluding alleged “alternate perpetrator” evidence. SUFFICIENCY OF THE EVIDENCE The Court of Criminal Appeals has expressed our standard of review of a sufficiency issue as follows:

When addressing a challenge to the sufficiency of the evidence, we consider whether, after viewing all of the evidence in the light most favorable to the verdict, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. Jackson v. Virginia, 443 U.S. 307, 319, 99 S. Ct.

2781, 61 L. Ed. 2d 560 (1979); Villa v. State, 514 S.W.3d 227, 232 (Tex. Crim. App. 2017). This standard requires the appellate court to defer "to the responsibility of the trier of fact fairly to resolve conflicts in the testimony, to weigh the evidence, and to draw reasonable inferences from basic facts to ultimate facts." Jackson, 443 U.S. at 319. We may not re-weigh the evidence or substitute our judgment for that of the factfinder. Williams v. State, 235 S.W.3d 742, 750 (Tex. Crim. App. 2007). The court conducting a sufficiency review must not engage in a "divide and conquer"

strategy but must consider the cumulative force of all the evidence.

Villa, 514 S.W.3d at 232. Although juries may not speculate about the meaning of facts or evidence, juries are permitted to draw any reasonable inferences from the facts so long as each inference is supported by the evidence presented at trial. Cary v. State, 507 S.W.3d 750, 757 (Tex. Crim. App. 2016) (citing Jackson, 443 U.S.

at 319); see also Hooper v. State, 214 S.W.3d 9, 16-17 (Tex. Crim.

App. 2007). We presume that the factfinder resolved any conflicting inferences from the evidence in favor of the verdict, and we defer to that resolution. Merritt v. State, 368 S.W.3d 516, 525 (Tex. Crim. App. 2012). This is because the jurors are the exclusive judges of the facts, the credibility of the witnesses, and the weight to be given to the testimony. Brooks v. State, 323 S.W.3d 893, 899 (Tex. Crim. App. 2010). Direct evidence and circumstantial evidence are equally probative, and circumstantial evidence alone may be sufficient to uphold a conviction so long as the cumulative force of all the incriminating circumstances is sufficient to support the conviction. Ramsey v. State, 473 S.W.3d 805, 809 (Tex. Crim.

App. 2015); Hooper, 214 S.W.3d at 13.

We measure whether the evidence presented at trial was sufficient to support a conviction by comparing it to "the elements of the offense as defined by the hypothetically correct jury charge for the case." Malik v. State, 953 S.W.2d 234, 240 (Tex. Crim. App.

1997). The hypothetically correct jury charge is one that "accurately sets out the law, is authorized by the indictment, does not unnecessarily increase the State's burden of proof or unnecessarily restrict the State's theories of liability, and adequately describes the particular offense for which the defendant was tried." Id.; see also Daugherty v. State, 387 S.W.3d 654, 665 (Tex. Crim. App. 2013). The "law as authorized by the indictment" includes the statutory elements of the offense and those elements as modified by the indictment. Daugherty, 387 S.W.3d at 665.

Zuniga v. State, 551 S.W.3d 729, 732-33 (Tex. Crim. App. 2018).

Daigneault complains the evidence was insufficient to support his conviction because there was no direct evidence that he was “solely and individually” responsible for intentionally causing Mandy’s death by shooting her. He contends the circumstantial evidence connecting him to Mandy’s murder was too speculative. We disagree with Daigneault.

In this case, the evidence supports the jury's verdict that Daigneault was the person who murdered Mandy. Daigneault and Mandy were cousins. Mandy brought Daigneault from Kansas to San Marcos, Texas, to live with her because she did not want to live alone. Only Daigneault, Mandy, and Titan, Mandy’s dog, lived in the apartment. She kept a handgun, a .380, one that her “Nana” gave her, in her apartment. Mandy considered taking Daigneault back to Kansas, however, after they had had an argument. In the days prior to her death, Mandy expressed fear of Daigneault to her father.

Robinson police responded to a reported brush fire shortly after 10:00 p.m. on April 5, 2023 in a residential development area that was still under construction. The fire was actually a burning corpse later identified as Mandy Rose Reynolds. Mandy’s dog, Titan, was observed running around at the scene of the fire. An urn containing the ashes of Mandy’s grandmother, which Mandy always kept in her purse, was found in the debris from the fire along with metal curtain rings, 1 the remains of a plastic and metal container, a container handle and clasp, and a shell casing from a .380 handgun. A resident near the scene had seen the fire as early as 9:20 p.m. About 10 minutes before the fire was observed by the resident, a car resembling Mandy’s black Honda Accord drove by two residences with Ring door cameras, appearing to be travelling in the

1 These rings matched the rings of one curtain found in a Penske moving truck also containing most of the contents of Mandy’s apartment. More of Mandy’s possessions, along with empty bottles of cleaning products were found in a dumpster nearest to Mandy’s apartment. Daigneault was seen loading items into the Penske truck and into Mandy’s car.

direction of the crime scene.

Shortly after an email notification was sent to Mandy’s email account stating that Robinson police had her dog, someone used Mandy’s cell phone to contact the Robinson Police Department. The caller attempted to impersonate Mandy in an effort to recover the dog. The authorities knew the caller was not Mandy, but instead was a male. Moments after police questioned the male caller’s claims, Mandy’s Facebook page was deleted. The detective who took the phone call later recognized the male’s voice as that of Daigneault. 2 Further, the detective had heard windshield wipers in the background during the first call, and a traffic camera image taken right before the phone call showed Mandy’s car driving through heavy rain in San Marcos.

The day before Mandy’s burned body was discovered, security video imaging from the parking lot showed that Daigneault drove Mandy’s Honda to a Walmart in San Marcos and bought a large blue and black plastic container. The container had a handle and a clasp like the handle and clasp found at the scene of the fire. Daigneault also bought a shovel and a gas can. Also, through the security video, Daigneault was seen placing the container in the Honda. He had originally tried to fit the tote in the trunk of the Honda, but the container was too big for the trunk. In the video, Daigneault was seen wearing

2 Diana, Mandy’s friend, also identified the caller’s voice as Daigneault.
