Florence Law was convicted of one count of lewd and lascivious conduct with a minor for having sexual intercourse with her grandson who was under the age of sixteen. Before trial, Law moved to suppress post- Miranda statements that she made to the police. The district court denied the motion. Law also filed a motion in liminе to exclude evidence that she had participated in the sexual molestation of her daughter when her daughter was a minor. However, the district court admitted the evidence. On appeal, Law challenges both of these rulings.
I.
BACKGROUND
Law was charged with lewd and lascivious conduct, Idaho Code § 18-1508, for having sexual intercourse with her grandson. According to the victim, the molestation began when he was twelve years old and continued for a period of three years. The victim’s trial testimony described the charged offense as follows. In 1993, when the victim was twelve and Law was sixty-three, the victim came to stay with his grandparents for the summer. One night, shortly after the victim’s аrrival, Law’s husband, who was naked at the time, roused the victim from sleep and asked him to come into his grandparents’ bedroom to give them massages. The victim went to the bedroom and massaged both grandparents’ backs. After the massages, the victim went back to bed, but his grandfather returned and asked the victim to go back to the bedroom. Once there, the grandfather told the victim to lie on the bed next to Law, who was naked and lying on her side. Law moved over in order to give the victim some room on the bed. After the victim lay down, the grandfather fondled the victim’s penis until it became erect. The grandfather then rolled the victim onto his side to face Law’s backside. Law parted her legs and her husband inserted the grandson’s penis into her vagina. The grandson then had sexual intercourse with Law.
According to the victim, this form of molestation by Law and her husband continued throughout that summer visit and during visits to his grandparents’ home during the next two summers. The sexual contact did not stop until the end of the summer of 1996 when the victim was рermanently moved to a juvenile facility.
In 1997, Law’s grandson reported the incidents of sexual intercourse to authorities, and Law and her husband were charged with lewd conduct. In pretrial motions, Law sought to suppress statements she had made to police and sought to preclude the State from introducing evidence that Lаw’s daughter (the victim’s aunt) had been sexually molested by Law and her husband. These motions were unsuccessful, and upon a jury trial, Law was convicted of lewd and lascivious conduct with her grandson.

ANALYSIS
A. Miranda Waiver
We first consider Law’s challenge to the admission of statements she made to the police during custodial interrogation. When reviewing the trial сourt’s ruling on a motion to suppress evidence on constitutional grounds, we defer to the trial court’s factual findings if they are supported by substantial evidence, but we exercise free review in determining whether, on those facts, constitutional standards have been satisfied.
State v. Cheatham,
1. Refusal to sign notification of rights form
Law was interrogated at the county jail in a tape recorded interview. An officer informed Law of her Miranda rights and then asked if she understood those rights. Law responded affirmatively. The officer then asked Law to sign a “notification of rights” form that included a waiver of the rights. The following exchange then occurred:
Officer 1: Sign this if you would like to talk about this situation.
Law: I would like to know what’s going on, аnd who’s doing it.
Officer 1: I need you- to sign that, then we can talk.
Law: That would be pushing me to sign papers.
Officer 1: This is your copy that you understand your rights.
Law: As long as I’m not being ...
Officer 2: All you’re signing is acknowledging that he read you your rights. That’s all you’re doing. That doesn’t mean anything else at all, and that you’re willing to talk to him now. You could stop talking to him at any time.
Law then signed the form.
Before the officers began asking her questions about the charged offense, they reminded Law sevеral times that she could terminate the interview at any point. The officers also asked Law whether she had memory problems and whether she was currently on any medication. Law denied having memory difficulties and said that she was taking a drug that had been prescribed for kidney problems. When asked if the medication was “mind altering,” Law told the officers that it did not affect her mental ability. The officers then began the interrogation, which continued for approximately thirty minutes, until Law terminated the interview on her own initiative. During the interrogation, Law said that if sexual intercourse with her grandson occurred, she must have been asleep at the time or must have thought that the other participant was her husband.
Law contends that her initial expression of reluctance to sign the notification of rights form implicitly expressed an unwillingness to speak to the officers and constituted an invocation of her right to remain silent. According to Law, because of this invocation of her right of silence, the officers were obligated to then cease their interrogation.
After a suspect has been advised of the right to remain silent and the right to counsel pursuant to
Miranda v. Arizona,
Nevertheless, police officers are not required to cease questioning unless the invocation of
Miranda
rights is clear and unequivocal. In
Davis v. United States,
Further, the rеfusal to sign a waiver form, standing alone, does not amount to an invocation of
Miranda
nor prevent a valid waiver of
Miranda
rights. In
North Carolina v. Butler,
Applying these standards, the record fully suрports the district comb’s determination that Law did not invoke her right to silence when she expressed reservations about signing the notification of rights form. Law’s comments were not an unequivocal invocation of her right to remain silent but appear to be an effort to gain information about the purpose of the form before she signed it — and perhaps an indication of “reluctance to put pen to paper.” Before Law began responding to officers’ inquiries about the charged offense, she had been fully informed of her Miranda, rights and acknowledged that she understood them. Because Law’s statements- about the form were ambiguous and did not express a desire to terminate the interview, they did not obligate the officers to cease the interrogation.
2. Use of prescription medication
Law also asserts that she lacked the capacity to make a knowing and intelligent waiver of her rights because she was under the influence of a prescription medication when she was interrogated.
A waiver of
Miranda
rights will be deemed valid only if it was made knowingly, voluntarily, and intelligently.
Oregon v. Elstad,
*726 B. Evidence of Molestation of Another Victim
Law’s daughter testified that on numerous occasions, when she was between the ages of nine and fourteen, Law held the daughter down, sometimes covering her mouth so she could not screаm, while Law’s husband (the daughter’s father) had sexual intercourse with the daughter. Law contends that this testimony should have been excluded under Idaho Rule of Evidence 404(b), which prohibits use of evidence of an individual’s uncharged misconduct to demonstrate a trait of character and show that the person acted in conformity with that trait. As Law acknowledges, however, evidence of other crimes, wrongs or acts is admissible for other purposes, including “proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident....” I.R.E. 404(b).
When the evidence of a defendant’s other crimes, wrongs, or acts is offеred, a two-part standard must be met. First, the evidence must be relevant to a material and disputed issue in the case; and second, the probative value of the evidence must not be substantially outweighed by the danger of unfair prejudice.
State v. Moore,
The district court held that the testimony of Law’s daughter was admissible to show intent, absence of mistake, and knowledge on Law’s part in the commission of the charged offense against her grandson. We agree with that assessment. The State bore the burden to prove that Law knowingly participated in the sexual molestation of her grandson “with the intent of arousing, appealing to, or gratifying the lust or passions or sexual desires” of Law or those of the child or of a third person. I.C. § 18-1508. The nature of the molestation reported by the victim in this case — with the grandfather being the active participant and Law lying passively while the grandfather inserted the child’s penis into Law’s vagina — was of such a nature that there was an issue as to whether Law knowingly participated or was asleep аnd unaware of the activity. Indeed, during her police interview, Law admitted that her grandson may have had intercourse with her but claimed that she either slept through the intercourse or believed that she was having intercourse with her husband rather than her grandson because the bedroom was dark. Therefore the testimony of Law’s daughter that Law had in the past been a willing and vigorous participant in sexual assaults on a child, in concert with her husband, had substantial probative value addressing the issue of whether Law knowingly and intentionally committed the charged offense.
In addition, the daughter’s testimony was relevant to corroborate the grandson’s testimony. It is by now well еstablished in Idaho law that, in view of the particular proof problems often presented in cases of sexual offenses against children, evidence of the defendant’s other sex offenses against minor victims may be relevant to substantiate the child victim’s testimony. The Idaho Supreme Court made this clear in Moore:
Although corrobоration is no longer mandatorily required in all sex crime cases, corroborating evidence may still be relevant, particularly in sex crime cases involving minor victims. Corroborative evidence in sex crime cases involving youthful victims is often times necessary to establishing the credibility of a young child. Too often the determinatiоn of the case rests strictly upon establishing that the victim’s testimony is more credible than that of the alleged perpetrator.
Evidence of similar acts of sexual misconduct between a defendant and the victim or between the defendant arid another witness is admissible for corroboration of the victim’s testimony in sex crime cases.
[State v. Schwartzmiller,]107 Idaho at 93 ,685 P.2d at 834 .
*727 Evidence of all the incidents of abuse, taken together, may provide an evidentiary plan or pattern that tends to make the alleged incidents more plausible and probable. Accordingly, we hold that the district court did not err in denying Moore’s motion in limine.
Id.
at 745-46,
Law argues that her daughter’s testimony is not relevant for the fоregoing purposes because the alleged abuse of the daughter was so remote in time — approximately twenty years prior to the charged offense — and because the described molestation is dissimilar with respect to the alleged activity of Law and the gender of the child victim. We, however, agree with the district court's determination that these factors do not render the testimony irrelevant. The lapse of time between the alleged victimization of Law’s daughter and the offense against the grandson, standing alone, does not necessarily make the daughter’s testimony inadmissible. The Idaho Supreme Court has stated that the issue of remoteness generally goes to the weight of the evidence, not to its admissibility.
Moore,
We acknowledge that there are differences between Law’s alleged acts with her daughter and those claimed by her grandson due to the difference in the gender of the victims, but there are also striking similarities. Foremost among them is the fact that as to both victims, Law acted jointly with her husband to effectuate an act of sexual intercourse with a child. In addition, the molestations occurred when the children were of similar ages, and the victims in both cases were family members residing, at least temporarily, in the home of Law and her husband. We therefore conclude that the district court did not err in holding that the daughter’s testimony was relevant.
With respеct to the balancing of the testimony’s probative value against the risk of unfair prejudice, we find no abuse of the trial court’s discretion. The district court clearly recognized the potential prejudicial effect of the daughter’s story, but held that its probative value was great and was not outweighed by the danger of unfair рrejudice. In reaching this conclusion, the district court perceived the issue as one of discretion, balanced the prejudicial effect of the daughter’s testimony against its probative value and came to a reasoned conclusion. Accordingly, we hold that the district court did not ero in admitting the testimony of Law’s daughter regarding uncharged incidents of sexual misconduct.
III.
CONCLUSION
The district court’s findings that Law did not invoke her Miranda rights by her initial reluctance to sign the notification of rights form and that Law knowingly, voluntarily, and intelligently waived her Miranda rights is supported by the evidence. We therefore affirm the district court’s denial of Law’s motion to suppress statements she made in the police interview. We also conclude that the district court correctly admitted the testimony of. Law’s daughter. Therefore, the judgment of conviction is affirmed.
