OAKLAND, Calif. (AP) — The hunt for a man police say killed an 18-year-old woman in an unprovoked knife attack in the San Francisco Bay Area ended where it began: In a train station.

John Cowell, 27, a recently paroled robber with a violent history, was peacefully arrested on an Antioch-bound train Monday night about a dozen miles from the Oakland station where investigators believe he killed Nia Wilson and wounded her sister Sunday night.

A phone call from a BART rider led police to stop and search a Richmond-bound train at the MacArthur Station in Oakland but Cowell wasn’t aboard, Bay Area Rapid Transit Police Chief Carlos Rojas said.

“About 10 minutes later after we got the call, another patron told us the subject got on an Antioch-bound train,” Rojas said.

That train was stopped at the Pleasant Hill station in Walnut Park, northeast of Oakland. Cowell was on board and was arrested without incident. It wasn’t immediately known if Cowell had a lawyer.
