IN THE SUPREME COURT OF THE STATE OF DELAWARE

MARCKENLEY GUSTAVE, § § No. 382, 2024 Defendant Below, § Appellant, § Court Below—Superior Court § of the State of Delaware v. § § Cr. ID No. 2101006788 (N) STATE OF DELAWARE, § § Plaintiff Below, § Appellee. §

Submitted: May 21, 2025 Decided: July 29, 2025

Before VALIHURA, TRAYNOR, and GRIFFITHS Justices.

Upon appeal from the Superior Court. AFFIRMED.

Eugene J. Maurer, Jr., Esquire, Molly R. Dugan, Esquire, EUGENE J. MAURER, JR.,

P.A., Wilmington, Delaware for Appellant.

Andrew R. Fletcher, Esquire, DELAWARE DEPARTMENT OF JUSTICE, Wilmington,

Delaware for Appellee.

VALIHURA, Justice: I. INTRODUCTION

After Marckenley Gustave was accused of sexually assaulting his eleven-year-old

cousin, I.G., he reached out to the police. During his recorded interview with Detective

Phillips, Gustave made incriminating statements, indicating that he was scared after I.G.

was taken to the hospital and that he had slept in I.G.’s bed with her on at least five

occasions. He offered no explanation for doing so. When Gustave later testified in his

own defense at trial and made contradictory statements, the State offered one short video

clip of his recorded interview during its cross-examination of him. The State later offered

both this video clip and another short video clip in its rebuttal case during direct

examination of Detective Phillips and referenced the contents of the video clips during

closing arguments. The State did not move to have the video clips admitted as State’s

exhibits until after the close of evidence, and the trial court ruled that they would be court

exhibits. After the trial court discovered that due to a clerical error, the video clips had

been mistakenly given to the jury, it promptly removed the video clips and gave the jury a

curative instruction. The trial court denied Gustave’s immediate motion for a mistrial.

The jury convicted Gustave of three counts of Rape First Degree and three counts

of Unlawful Sexual Contact First Degree. Gustave timely moved for a new trial on the

same grounds, which the trial court also denied. Gustave was sentenced to 81 years of

incarceration and now appeals his conviction. We conclude that the trial court applied the

correct standards to evaluate Gustave’s motions, and we agree that Gustave failed to

demonstrate the required prejudice. Accordingly, we AFFIRM Gustave’s convictions.

2 II. FACTUAL AND PROCEDURAL BACKGROUND

A. Factual Background

On January 13, 2021, eleven-year-old I.G. told her mother for the first time that

Marckenley Gustave, the mother’s 22-year-old cousin, had been raping her.1 I.G. moved

to the United States from Haiti when she was in third grade. She first lived in New Jersey

and then in Delaware, where she finished elementary school.2 Gustave had been living

with I.G. and her mother since shortly after I.G. moved to Delaware, while I.G. was still in

elementary school. Because I.G.’s mother worked the swing shift, from approximately

3:00 in the afternoon until midnight each day, I.G. was often home alone with Gustave after

school.

I.G. testified about five separate occasions when they were home alone together and

Gustave sexually assaulted her. The sexual assaults began when I.G. saw Gustave

masturbating in the living room while he was watching pornography.3 In the first incident,

after I.G. saw Gustave masturbating, Gustave asked her if she wanted to touch his penis,

wrapped her hand around his penis, and had her put her mouth on his penis.4 Gustave

pushed her head down, but I.G. stopped when he ejaculated because she did not like the

1 App. to Opening Br. at A50, A60. There was some confusion about I.G.’s age as of January 2021 in the briefs and in her trial testimony, but I.G. testified clearly that her date of birth is August 26, 2009. Id. at A50 (I.G. Test.). 2 Id. at A50–52 (I.G. Test.). 3 Id. at A63 (I.G. Test.). 4 Id. at A64 (I.G. Test.).

3 taste of semen.5 After this incident, Gustave purchased gum for I.G. to use when

performing oral sex on him.6 Gustave also communicated with I.G. via text about their

sexual contact, asking her if she wanted to engage in sexual activities when he got home

and offering to buy her gum because he knew she did not like the taste of semen.7

In the second incident, Gustave got into bed with I.G., put his mouth on her breast,

and wrapped her hands around his penis.8 In the third incident, Gustave found I.G. in her

bedroom, asked if she wanted to “try something,” then removed their clothes and partially

inserted his penis into her vagina.9 In another incident, Gustave made her bend over her

bed and tried to insert his penis into her vagina.10

In the final incident, I.G. was playing video games in the living room when Gustave

asked her, “Do you want to do it?”11 She said no and told him she was on her menstrual

cycle. Gustave then pulled his pants below his knees, removed I.G.’s pants and underwear,

put her on top of him, and tried to insert his penis into her vagina. 12 I.G. told him again

that she did not want to engage in sexual activities with him, got off of him, and went back

5 Id. at A64–65 (I.G. Test.). 6 Id. at A80–81 (I.G. Test.). 7 Id. at A75–76 (I.G. Test.). 8 Id. at A65–66 (I.G. Test.). 9 Id. at A67–68 (I.G. Test.). 10 Id. at A69 (I.G. Test.). 11 Id. at A70 (I.G. Test.). 12 Id. at A72–73 (I.G. Test.).

4 to playing video games. Gustave then inserted two fingers and “played” with her vagina

while he masturbated.13

About a week later, I.G. told her mother about the sexual abuse for the first time.14

After I.G. told her mother, her mother called the police and took I.G. to Nemours Children’s

Hospital to undergo a rape examination.15 I.G.’s physical examination showed no signs of

physical trauma, but her urine and swab tests showed a positive result for chlamydia.16

The next day, Detective Christopher Phillips interviewed Gustave at the police

station.17 During the interview, which was recorded, Gustave told Detective Phillips that

he was afraid because I.G. had been taken to the hospital and that he had slept in I.G.’s bed

on five occasions but could not provide an explanation for doing so.18 While at the police

station, Gustave agreed to provide a urine sample, which also showed a positive result for

13 Id. at A74 (I.G. Test.). 14 Id. at A75 (I.G. Test.). The examining forensic nurse at Nemours Children’s Hospital testified that I.G. told the examining physician that the last sexual assault had occurred about three days prior to her examination, on January 10, 2021. Id. at A102 (Gorman-Zolochik Test.). 15 Id. at A170 (Regina Gustave Test.). 16 Id. at A110–11 (Gorman-Zolochik Test.), A134–35 (Deutsch Test.). Gorman-Zolochik, an emergency and forensic nurse at Nemours Children’s Hospital, testified that “[i]t’s very typical to have no signs or trauma following any form of sexual assault.” Id. at A111 (Gorman-Zolochik Test.). With respect to the chlamydia testing, Dr. Deutsch explained that “the initial study that is run by the Nemours lab is referred to as a screening test, and then there’s a subsequent confirmatory test that’s a second test that’s run on the sample that is processed by an external lab.” Id. at A135 (Deutsch Test.). The second test on the same sample done by an external facility “eliminates the possibility that the lab test is inaccurate.” Id. (Deutsch Test.). 17 Id. at A213 (Phillips Test.). 18 Id.
