King County prosecutors charged a Kent man on April 13 with second-degree rape of a 17-year-old Federal Way girl.

Convicted sex offender Andrew Jason Trotman, 38, allegedly raped his teenaged son’s girlfriend while she was unconscious on March 28.

He’s being held on $500,000 bail.

Police were called to St. Francis Hospital on March 29 after staff reported the girl had been raped.

In an interview, the girl told investigators she was riding with her 20-year-old boyfriend, his father, a 16-year-old girl and an 18-year-old girl — thought to be another victim — in a car. Trotman was driving the car and allegedly passed around a bottle of alcohol, encouraging everyone to drink.

The girl said it appeared Trotman pretended to drink when he took swigs from the bottle.

The car got a flat tire and the girl’s boyfriend went out to check on it. When he did this, the girl told police Trotman started to play with the 18-year-old’s hair and squeeze her leg until she told him to stop. He then allegedly turned his attention to the 17-year-old victim and squeezed her leg, “saying comforting things about the flat tire, despite [her] not crying or showing any other signs of distress.” The girl told him to stop but he didn’t until his son got back in the car. The 18-year-old said Trotman tried to kiss her and said they could get together and no one would have to know. She felt uncomfortable and called her sister to come get her and the 17-year-old victim.

But the 17-year-old felt sick, got out of the car and started to vomit.

This allegedly prompted Trotman to ask for her phone so he could call for a taxi or a tow truck. She gave him her phone but then realized it was strange because he had his own phone.

After he returned her phone and the two victims had been picked up by the 18-year-old’s sister, the 17-year-old was finally home. Court documents do not indicate what happened to the 16-year-old girl.

The victim locked her apartment door and went to bed but noted her boyfriend had left her a voicemail.

“… But she really could not understand what he was saying and stated that he sounded extremely intoxicated,” the charging documents state. “She texted [her boyfriend] and told him she would leave her window unlocked and he could come in the window.”

The girl told police she fell asleep at about 9:30 p.m. When she awoke later, she said someone was in bed with her, who she thought was her boyfriend.

However, one side of her pants and underwear was off, she felt pain in her groin area and there was evidence of having just had sexual intercourse.

As she went to the bathroom, the person in bed with her awoke and it was Trotman, the court documents state.

She asked where her boyfriend was and Trotman told her he was still trying to fix the car tire. The girl claims he didn’t explain why he was there and quickly left through the window.

“[The victim] believes Trotman entered through the window while she was sleeping because only she and her mother have keys to the apartment and the front door was secured with a deadbolt and chain,” the documents continue.

The girl told police she doesn’t have any memory between 9:30 p.m. and 3:40 a.m. and that she had never said or done anything to make Trotman think she wanted to have sex with him.

“[The victim] stated that she thought that Trotman was strange because he would always hang out with [her boyfriend] and [he] would flirt with her and her young friends,” court documents state.

She called her friend and was soon driven to the hospital after Trotman left.

Nurses at St. Francis performed a rape kit and noted evidence of rape.

When police interviewed the girl’s boyfriend, he was at first reluctant to speak and said he was “torn between his girlfriend and his father.”

Ultimately, he told police he and his father planned to go to his aunt’s house after the girls left them. But “at one point he believes he passed out near an overpass.”

The boyfriend eventually got to his aunt’s who told him she had not seen his father.

“[The victim’s boyfriend] stated that it was after this that he learned from [his girlfriend] what had happened,” the documents continue. “He and [the victim] felt that Trotman had created a diversion for him by sending him to their aunt’s home.”

The two had been dating since August 2014, the victim told police. The girl knew her boyfriend’s father had been to prison but her boyfriend had “failed to inform” her he was a sex offender.

Trotman was convicted of attempted promotion of commercial sex abuse of a minor and unlawful imprisonment in 2010, failure to register as a sex offender in 2013, attempting to elude, several assault convictions and forgery, among others.

“In addition, the state is aware of a very serious allegation against the defendant from 2013 in which the defendant is alleged to have beaten and raped a teenage girl, while trying to force her to engage in prostitution,” court documents state.
