March 17, 2026

IN THE COURT OF APPEALS OF THE STATE OF WASHINGTON

DIVISION II

STATE OF WASHINGTON, No. 59524-9-II

Respondent,

v.

DEREK PAUL RILEY, JR., UNPUBLISHED OPINION

Appellant.

MAXA, P.J. – Derek Riley, Jr. appeals his convictions of first degree child rape, second

degree child rape, first degree child molestation, and second degree child molestation and his

sentence. The convictions arose from Riley’s sexual abuse of his stepdaughter over a period of

several years.

We hold that (1) as the State concedes, the prosecutor improperly asked Riley whether

witnesses were lying, but Riley cannot show prejudice; (2) the prosecutor did not comment on

Riley’s right to remain silent; (3) the prosecutor did not improperly minimize the burden of proof

during closing argument; (4) the prosecutor did not improperly vouch for the credibility of the

victim and her mother during closing argument; (5) as the State concedes, the prosecutor

improperly vouched for the credibility of the State’s case during closing argument, but Riley

waived his challenge by failing to object; (6) Riley’s claim that he received ineffective assistance No. 59524-9-II

of counsel because his defense counsel did not move for a mistrial when three witnesses gave

opinions that Riley was guilty fails; (7) cumulative error does not require a new trial; and (8)

four challenged community custody conditions must be addressed on remand consistent with this

opinion.

Accordingly, we affirm Riley’s convictions, but we remand for the trial court to address

the challenged community custody conditions consistent with this opinion.

FACTS

Background

Riley and Faith Riley married in 2006. Faith1 had a daughter, RB (born September

2002), from a previous relationship. Riley had two children from a previous relationship. One

of Riley’s children was Erik Watson, who was about four years older than RB. When Riley and

Faith married, Riley, Faith, RB, and Watson were living in one household in Vancouver.

In April 2010, when RB was seven, Child Protective Services (CPS) was called after RB

suggested to a friend that Riley had touched her genitals. The police arrived to take RB into

protective custody. Riley told Faith, “Don’t say anything. Don’t tell them anything.” Rep. of

Proc. (RP) at 682-83. When RB was interviewed, she denied that anything had happened. RB

was returned home three days later.

In August 2020, RB disclosed to Faith that Riley had been sexually abusing her. RB

described multiple incidents of molestation and sexual intercourse by Riley while they lived

together. Following the investigation, the State charged Riley with first degree child rape,

second degree child rape, first degree child molestation, and second degree child molestation.

1 Because Riley and Faith have the same last name, we refer to Faith by her first name. No disrespect is intended.

Trial

At trial, RB testified that Riley first molested her when she was seven years old, when

Riley pulled her pants down and licked her vagina. RB testified that she later told her friend JM,

that Riley had done stuff to her.

RB recalled that not long after, police came to her house in April 2010 to take her away.

Before she left, Riley took her into another room and instructed her not to tell anyone what had

happened to her. He said he did not want to get in trouble and she “didn’t want to know what

would happen if things had gotten brought out.” RP at 484. RB stated that when she was

interviewed, she said that nothing had happened because Riley told her not to tell anyone.

RB testified that after that, there were multiple occasions when Riley would touch and

lick her vagina. RB further testified that Riley inserted his finger in her vagina when she was

around nine years old. And when Riley found out that RB had sex with a boy when she was 13,

RB testified that Riley began inserting his penis into her vagina. This occurred repeatedly until

2020.

Vancouver Police officer Rotha Yong testified about coming to Riley’s house in April

2010 to take custody of RB. She testified that Riley told Faith, “Don’t say anything. Don’t tell

them anything.” RP at 682-683. Riley objected based on a standing objection that this testimony

involved Riley’s exercise of his right to remain silent.2 The trial court noted the objection.

Faith testified that RB disclosed in August 2020 that Riley had abused her. Later, Faith

testified that she divorced Riley “[b]ecause he raped [RB].” RP at 776. Riley objected and the

2 Before trial, Riley filed a motion in limine to exclude this testimony because it was a comment on his right to remain silent. The trial court reserved ruling on the issue.

3 No. 59524-9-II

trial court sustained the objection, instructing the jury that Faith was not allowed to state a legal

conclusion about rape.

JM testified that sometime in 2010, RB disclosed that Riley was touching her. JM told

her mother and then talked with CPS people. When JM was in high school, she reached out to

RB because she thought RB might still be in danger. JM said that the first time RB said nothing

happened, but the second time “she was a little more honest.” RP at 670. At that point, Riley

objected, and the trial court instructed the jury to disregard the last portion because witnesses are

not allowed to comment on another witnesses’ honesty.

Watson testified that we he was around 12 years old, he heard Riley call RB “sexy.” RP

at 696. Watson later testified that he no longer had a relationship with Riley. He stated, “[W]hat

had happened to [RB] was kind of the thing that is kind of unforgivable, you know. So it was

something that I didn’t ever really want to talk to him again.” RP at 700. Riley objected, and the

trial court instructed the jury to disregard the statement.

Riley testified and denied ever touching RB inappropriately or forcing her to have sexual

intercourse with him.

During cross-examination, the prosecutor asked Riley whether his son, Watson, testified

falsely when he stated he heard Riley call RB “sexy.” RP at 767. Defense counsel objected,

arguing that Riley was not permitted to comment on another witness’s veracity. The trial court

overruled the objection, stating that there was a factual discrepancy and that broadened cross-

examination was permitted. Riley testified that Watson obviously was mistaken in what he

heard.

The prosecutor then asked Riley whether it was Riley’s testimony that RB was “making

everything up.” RP at 767. Defense counsel did not object. Riley responded that he believed

4 No. 59524-9-II

RB had assistance in making up what she said. The prosecutor continued by asking whether RB

was an actress. Riley testified that RB was “a very good actor.” RP at 768.

The prosecutor then asked if Faith was an actress. Defense counsel objected that the

question was not relevant. The trial court overruled the objection. Riley testified that Faith “puts

on a relatively good show” for people at church and that “she is a very good actor without any

formal education in acting.” RP at 768.
