PEOPLE OF THE STATE OF MICHIGAN, UNPUBLISHED February 10, 2026 Plaintiff-Appellee, 11:52 AM

V No. 370342 Lapeer Circuit Court WILLIAM GRANT MANN, LC No. 2022-014196-FC

Defendant-Appellant.

Before: RICK, P.J., and YATES and MARIANI, JJ.

PER CURIAM.

Defendant, William Grant Mann, was convicted by a jury of sexually abusing his daughter, TS, when she was young. Throughout the trial, the prosecution consistently argued that defendant committed the crime of first-degree criminal sexual conduct (CSC-I), MCL 750.520b(1)(a) (victim under 13 years of age), by making TS perform fellatio on him. But the prosecution was less clear about the theory that supported the charge that defendant committed second-degree criminal sexual conduct (CSC-II), MCL 750.520c(1)(a) (victim under 13 years of age), with TS. Nonetheless, the jurors convicted defendant of both CSC-I and CSC-II, and defendant was sentenced to serve 25 to 40 years in prison for the CSC-I conviction, and 5 to 15 years in prison for the CSC-II conviction, to be served concurrently. On appeal, defendant challenges both of his convictions, but neither of his sentences. We affirm the conviction of CSC-I, but vacate the conviction of CSC-II and remand the case for further proceedings on the CSC-II charge only.

I. FACTUAL BACKGROUND

TS was born in August 2001. She initially lived with her parents and siblings in a trailer. In December 2011, she moved with her family to a house in Lapeer. TS described her relationship with defendant as similar to “a boyfriend/girlfriend relationship.” She said that, before her family moved, defendant told her to use a vibrator while he watched her. After TS and her family moved, TS explained that defendant would ask her, “[w]hat do I get in return?” if she wanted something. According to TS, defendant meant he “wanted a hand job or a blow job[,]” so TS would “rub [her] hand up and down his penis until he came.” She testified that that first happened when she was “10 or 11” years old, and it took place “every couple weeks.” TS stated that the abuse occurred in

-1- defendant’s bathroom, on his bed, or in a hot tub that was “in the master bedroom right next to the bathroom.” TS testified that defendant “had me come into the hot tub with him clothingless, and he would have me give him a hand job as he touched my clitoris.” TS’s mother, T. Pack, testified that the hot tub in the master bedroom did not work until a year or two after the family moved into the house in Lapeer in December 2011.

TS also testified that defendant “would have [her] put [her] mouth on his penis” when she was 11 years old. She stated “he would grab the back of my head by my hair [and] push my head back and forth.” TS further explained that when she was 11 years old, defendant “put his penis on my vagina” and had her “slide back and forth.” According to TS, that occurred “in the bath tub of the master” bathroom, but Pack and TS’s brother, WLM, testified that there was no bathtub in the master bathroom. During the time that the sexual activities were taking place, defendant told TS: “You can’t say anything to anybody. If you do I’ll get taken away from you. You don’t want your dad being taken away from you, do you? What about your siblings? Just promise me you won’t say anything.”

TS testified that the assaults stopped when she was 13 years old because she started having periods, and defendant said to her “[t]hat’s gross.” Years later, in May 2021, TS moved out of her family’s house and began going to counseling. She told her counselor “about some of the problems that I was having living on my own.” When the counselor asked TS “what could trigger that,” TS told her about defendant’s abuse. TS initially indicated that she had not talked to defendant since she moved out, but she later stated that defendant did visit her house with her siblings.

Defendant was first charged in a criminal complaint filed in October 2021 with two counts of CSC-I, the first count under MCL 750.520b(1)(a) (victim under 13 years of age), and the second count under MCL 750.520b(1)(b)(ii) (victim between 13 and 16 years of age and defendant related to victim). At the preliminary examination, TS testified that defendant “asked me to perform oral sex” when she was “around nine” years old in “2008.”1 She stated that the incident when defendant “rubbed his penis against [her] vagina” took place when she was “[a]round nine or ten” years old. Based on that testimony, the district court permitted the prosecution to amend the second count to include a charge of CSC-II, under MCL 750.520c(1)(b)(ii) (victim between 13 and 16 years of age and defendant related to victim).

In March 2022, the prosecution filed a two-count information against defendant. Count 1 alleged CSC-I by “sexual penetration, to-wit: Defendant’s Penis to Victim’s Mouth, with a child under 13 years of age,” whereas Count 2 charged “sexual contact” with TS, a “victim being at least 13 but less than 16 years of age. . . .” The prosecution filed a first amended information in February 2023. In that amended information, the CSC-I charge in Count 1 remained the same, alleging that defendant engaged “in sexual penetration, to-wit: entry into Victim’s mouth by Defendant’s Penis, with a child under 13 years of age . . . .” But the CSC-II charge in Count 2 was revised to accuse defendant of “sexual contact with a person under 13 years of age . . . .” The prosecution amended the information again before trial in November 2023. The second amended information contained the same CSC-I charge in Count 1, accusing defendant of engaging “in sexual penetration, to-wit: entry into Victim’s mouth by Defendant’s Penis, with a child under 13 years of age . . . .” Likewise,

1 TS was born in 2001, so she could not have been nine years old in 2008.

-2- Count 2 of the second amended information set forth the same CSC-II charge as the first amended information, alleging that defendant “did engage in sexual contact with a person under 13 years of age . . . .” Defendant’s trial began one week after the second amended information was filed.

At defendant’s trial, the trial court instructed the jury on the nature of the CSC-I charge in Count 1, stating that the prosecution had to prove “that the Defendant engaged in a sexual act that involved entry into [TS]’s mouth by the Defendant’s penis.” That language matched the allegation in Count 1 of the information. But the trial court’s instructions on the CSC-II charge in Count 2 gave the jury two options, stating that “the prosecutor must prove . . . that Defendant intentionally touched [TS]’s genital area or intentionally made [TS] touch his genital area.” The jury convicted defendant on both counts, and the trial court thereafter sentenced defendant to concurrent terms of imprisonment on the two counts of conviction.

After defendant appealed to this Court, he filed a motion in the trial court for a new trial or a Ginther2 hearing. In that motion, defendant contended that his convictions were against the great weight of the evidence because TS’s trial testimony “was heavily impeached and contradicted on key points.” Defendant further asserted that his trial counsel was ineffective for: (1) not adequately impeaching TS; (2) not adequately impeaching Pack or moving for a mistrial; (3) not requesting a specific unanimity instruction; and (4) not moving to inspect TS’s counseling records.3 Defendant attached text messages that he and TS exchanged from May 2021 to August 2021, which defendant allegedly gave to his attorney before trial.
