COURT OF APPEALS

PEOPLE OF THE STATE OF MICHIGAN, UNPUBLISHED July 16, 2026 Plaintiff-Appellee, 11:42 AM

V No. 365742 Kent Circuit Court DENNIS DAWAYNE SLAGEL II, LC Nos. 21-007794-FC; 21-007854-FH Defendant-Appellant.

Before: ACKERMAN, P.J., and REDFORD and FEENEY, JJ.

PER CURIAM.

Defendant appeals as of right his jury trial convictions for (1) first-degree criminal sexual conduct (CSC-I), MCL 750.520b(1)(a); MCL 750.520b(2)(b) (victim under 13, defendant over 17); (2) second-degree criminal sexual conduct (CSC-II), MCL 750.520c(1)(a); MCL 750.520c(2)(b) (victim under 13, defendant over 17); and (3) fourth-degree criminal sexual conduct (CSC-IV), MCL 750.520e(1)(a) (victim between 13 and 15, defendant five or more years older). The trial court sentenced defendant to serve concurrent sentences of (1) 25 to 40 years, (2) 10 to 15 years, and (3) 13 months to 2 years in prison, respectively. Defendant is subject to mandatory sex-offender registration and lifetime electronic monitoring. We affirm.

I. FACTS

This case arises out of defendant’s sexual abuse of JR.1 The CSC-I and CSC-II acts occurred in the period of January 1, 2015 to December 31, 2015, at a home on Straight Avenue in Grand Rapids, Michigan, while JR was under the age of 13, and defendant was over the age of 17. The act of sexual penetration for the CSC-I charge was alleged to be “oral/penile . . . .” The CSC- IV act occurred in the period of January 1, 2021 to June 2, 2021, at a home in Walker, Michigan,

1 JR identifies as nonbinary and uses they/them/their pronouns. The trial court and the parties have therefore used they/them/their pronouns when referring to JR, and we will do likewise.

-1- while JR was between the ages of 13 and 15, and defendant was more than five years older. At the times of the sexual abuse, defendant was the boyfriend of JR’s mother, JS.

JR testified at trial that they could not remember whether the oral penetration occurred. But JR testified about the surrounding circumstances. When JR was in third grade, JR and defendant were alone in the living room while JS was sleeping upstairs. JR wanted a piece of candy that consisted of a sucker and a liquid that was to be squirted on the sucker. Defendant asked JR to lick the candy off his penis. JR ate some of the candy and remembered that it tasted like blue raspberry, but at trial, JR could not remember if they ate the candy off defendant’s penis. JR testified that defendant habitually used candy or toys to bribe or manipulate JR to participate in sexual acts. While JR was in third grade, JR told JS about the sexual abuse by defendant, but JS did nothing to help JR. JR and JS no longer had a relationship at the time of trial.

At trial, evidence was presented that JR disclosed the oral penetration to two friends. In 2017, JR told MM about the oral penetration. MM reported JR’s disclosure to school authorities, but JR then denied the abuse when questioned by a school counselor and a forensic interviewer in 2017. On June 1, 2021, JR disclosed the oral penetration to another friend, AC, in an e-mail. The e-mail chain was admitted into evidence as an exhibit by stipulation of the parties, and relevant portions of the e-mails were read into the record as the prosecutor questioned AC. JR’s e-mail disclosure came after a Memorial Day 2021 family gathering at which family members, including JR’s aunt SS, discussed with JR ways to get JR out of JS and defendant’s home due to poor conditions in the home. Following the e-mail disclosure, AC reported the abuse to school authorities. JR was removed from JS and defendant’s home and placed in the home of SS and her wife. JR was forensically interviewed in 2021 and disclosed the oral penetration. JR’s statements in the 2021 forensic interview were used to impeach JR’s trial testimony that they did not remember the oral penetration.

Thomas Cottrell testified as a prosecution expert in child sexual abuse dynamics and offender tactics. He provided general testimony about common behaviors of child victims of sexual abuse.

The defense theory at trial was that JR fabricated the allegations to be removed from the home because JS and defendant did not support JR’s transgender status and JR wanted to live with their aunts who were members of the LGBTQ community.

Defendant was convicted and sentenced, as stated earlier. Thereafter, defendant moved for a new trial and to correct an invalid sentence, making many of the same arguments he now asserts on appeal. Following a Ginther2 hearing regarding defendant’s ineffective-assistance-of-counsel claims, the trial court rejected defendant’s arguments and denied his motion. Defendant now appeals.

II. ADMISSIBILITY OF EXPERT TESTIMONY

2 People v Ginther, 390 Mich 436; 212 NW2d 922 (1973).

-2- On appeal, defendant argues that the trial court abused its discretion by denying his motion to exclude Cottrell’s expert testimony. We disagree.

A. PRESERVATION AND STANDARD OF REVIEW

Defendant preserved this issue by moving to exclude Cottrell’s expert testimony from trial. See People v Unger, 278 Mich App 210, 216; 749 NW2d 272 (2008). We review a trial court’s decisions regarding the qualification of an expert and the admissibility of expert testimony for an abuse of discretion. Id. A court abuses its discretion when its decision falls outside the range of reasonable and principled outcomes. Id. at 217. A “court necessarily abuses its discretion when it makes an error of law.” People v Everett, 318 Mich App 511, 516; 899 NW2d 94 (2017).

B. ANALYSIS

At the time of trial,3 MRE 702 provided as follows:

If the court determines that scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education may testify thereto in the form of an opinion or otherwise if (1) the testimony is based on sufficient facts or data, (2) the testimony is the product of reliable principles and methods, and (3) the witness has applied the principles and methods reliably to the facts of the case.

“MRE 702 incorporates the standards of reliability established in Daubert v Merrell Dow Pharm, Inc, 509 US 579; 113 S Ct 2786; 125 L Ed 2d 469 (1993).” People v Muniz, 343 Mich App 437, 443; 997 NW2d 325 (2022). “The trial court . . . acts as a gatekeeper for expert testimony and has a fundamental duty to ensure that the proffered expert testimony is both relevant and reliable.” Id. (quotation marks and citation omitted). The inquiry is flexible considering the differing kinds of experts, “and a court determining the admissibility of expert testimony may consider reliability factors pertinent to the particular type of expert testimony offered and its connection to the particular facts of the case.” People v Kowalski, 492 Mich 106, 120; 821 NW2d 14 (2012). “The expert’s opinion must be shown to be reliable, including the data underlying the expert’s theories and the methodology by which the expert draws conclusions.” Muniz, 343 Mich App at 444. “The preliminary determination of the qualification of an expert is for the trial court.” Id. at 443.

“Michigan courts regularly admit expert testimony concerning typical and relevant symptoms of abuse, such as delayed reporting and secrecy.” Id.
