King County prosecutors have filed charges against a Fall City man and a Maple Valley woman for raping and molesting a young child over a nearly two-year period.

Prosecutors filed charges Monday, Sept. 8, against Richard Stuart Trombley, 27, of Fall City, and Makayla Elaine Everson, 26, for rape of a child in the first degree and child molestation in the first degree.

Charging documents filed in King County Superior Court say that in late 2011, when Trombley became involved with Everson, he and then she began sexually abusing Everson’s then-5-year-old daughter. Trombley lived with Everson and her daughter at a house in the 33100 block of Southeast 42nd Street in Fall City.

“This sexual abuse occurred over 100 times during the course of a two-year period,” charging papers state.

Both defendants were addicted to heroin, court papers stated. Trombley allegedly allowed other men to photograph and videotape the girl naked in exchange for drug money, according to the documents.

Court probable-cause papers relate that when Everson went into a rehab facility in California, her biological father took custody of their daughter; he and the girl’s stepmother began to notice signs of the years of abuse. She showed her stepmother how to use heroin, and the stepmother found a sexually explicit video of the girl on her iPad. When investigators talked to her, the girl related nearly two years of abuse. According to court papers, she also told detectives that she was rarely fed, and was supposed to get a daily supplement in a feeding tube in her stomach, but didn’t. Her stepmother said she weighed 36 pounds when she came to live with them.

According to the charging papers, Trombley also allegedly kissed Everson’s 8-year-old niece, telling her not to tell anyone or he would hit her. Charging papers do not identify any other alleged victims.

On Thursday, Sept. 4, Trombley was arrested by police, who found three grams of heroin in the car; he denied sexually assaulting the girl. He was booked into King County Jail that day. Everson was booked into jail on Sept. 8. Both are being held on $250,000 bail.

An arraignment is scheduled for Monday, Sept. 22.
