Detectives are searching for the man identified as the suspect in the Saturday, May 30th incident in which a woman was dragged by a Lyft ride share car after she said the driver attempted to extort sex from her and would not return her phone.

Kevin Jun Chau, 38, has been charged with second degree robbery. The Pioneer Square resident is wanted on a $100,000 warrant.

King County prosecutors say Chau committed the crime “with sexual motivation.” “The defendant abused the victim’s trust as a car service driver by not only withholding her property but insisting on sexual services and later assaulting her,” they write.

According to the SPD report included in the charging documents, police say Chau picked up his victim around 1 AM at Big Mario’s and drove her to her Central District apartment. The victim told police she arrived home after the 12-minute ride and realized she left her phone in the car. The victim called the suspect multiple times from her iPad but says the suspect hung up on her before finally asking her, “What are you going to do for it?” and then asked “Will you fuck me?” The victim told police she agreed to the driver’s demands and told him to return to where he dropped her off. When he arrived, the driver asked the victim, “Are you going to fuck me?” She told police she could see her driver “Kevin” holding the phone inside the car. The victim said she began to reach into the car to grab her phone and lied that she had a picture of the car’s license plate and that she had called the police. The victim said Kevin suddenly started to drive away. “When she reached inside his vehicle to retrieve her phone, the driver sped away, dragging the woman a short distance down the street, leaving her with cuts on her legs, feet, arms and hands,” police say.

The prosecutor’s office says Chau’s attorney Kevin Trombol contacted SPD earlier this week and “the police gave the defendant the opportunity to turn himself in” but “he did not do so.” According to the charging document, Trombol told police his client claims the victim was “drunk, and impossible to deal with.” “Trumbol also stated that Chau understands he made a mistake by not retuming the cell phone and is willing to make restitution by buyrng a new phone,” the report from Detective Shandy Cobane notes.

A Lyft spokesperson tells CHS the company shared the driver’s information with detectives and is cooperating in the investigation following a subpoena for the records. The ride service company also released a statement on the investigation:

We take all matters involving safety extremely seriously. We immediately disabled the driver’s account upon receiving this troubling report. Our Trust and Safety team has been in touch with the passenger and we will continue to help in any way we can, as well as support the authorities in the ongoing investigation.

Police are now looking for the public’s help in finding Chau. If you have information, SPD asks that you call 911.
