Sheriff detectives arrested a 22-year-old Skyway man on Jan. 8 for investigation of rape, robbery and kidnapping, according to the King County Sheriff’s Office.

Detectives believe the man committed at least two other rapes and perhaps more, according to Sgt. John Urquhart, a sheriff’s spokesman.

The suspect was in the Regional Justice Center Jail in Kent on a $500,000 bail. Charges are pending.

In a Jan. 7 incident, the 26-year-old victim was in Skyway to respond to an ad posted on Craigslist for a “nude model.” Detectives believe the ad was posted by the suspect.

When the woman pulled into a parking lot about 9 p.m. to use her cell phone, the suspect suddenly appeared, got into her car and held a knife to her throat, according to Urquhart. The suspect made her drive around for a short period of time before telling her to pull over. Then he forced her to perform a sex act, according to Urquhart. He took items from the car and the woman.

Detectives identified a fingerprint which was found in the victim’s vehicle. They arrested the suspect on Jan. 8 as he left his Skyway residence.

A similar case occurred in Skyway on Dec. 20. In that case the suspect reportedly got into the car while the 21-year-old victim was stopped at a red light. Again he held a knife to her throat and eventually had her perform a sex act, according to Urquhart. Detectives believe it is likely the same man is responsible for this rape as well and are doing additional follow-up work, according to Urquhart.

On Dec. 9 two women went to Skyway as a result of their Craigslist ad and were sexually assaulted by a man whose actions and description matched the other two cases. That investigation is also continuing.

Due to the connection to Craigslist in at least two of these cases, it is a possibility there are other victims who may not have reported the crime, according to Urquhart.

Any additional victims should call the Sheriff’s Office at 206-296-3311 (24 hours) or 911 to report the crime.
