Police Seek Suspect In Witness Tampering

The Clackamas County Sheriff's Office is asking for help finding a suspect in a witness tampering incident in a fatal hit and run case.

After being released from Clackamas County Jail, fatal hit-and-run suspect Kevin Charles Derrick and his girlfriend Alysha Raeann Esser allegedly confronted, physically assaulted and injured a witness in the case.

The Clackamas County Sheriff's Office says it appears the assault was intended to deter the witness from testifying against Derrick.

Since that assault, Kevin Derrick has once again been located and arrested -- this time on a charge of Tampering with a Witness -- and booked at the Clackamas County Jail. His total bail is now $1 million.

Investigators are still trying to locate Esser who is a suspect in the witness-tampering assault.

There is currently a felony warrant for Esser's arrest on a charge of Tampering with a Witness out of Clackamas County Circuit Court.

If you know Alysha Esser's whereabouts, call Non-Emergency Dispatch at 503-655-8211. You can also contact the Sheriff’s Office Tip Line — by phone at 503-723-4949 or by using the online email form at https://www.clackamas.us/sheriff/tip . Please reference CCSO Case # 20-020162.

The fatal crash happened September 19 on Southeast King Road. 59-year-old Robert Keys, of Gladstone, was hit and died at the scene.
