FOLSOM, Calif. (AP) _ A convicted murderer who escaped Folsom Prison through a storm drain more than 1 1/2 years ago has been arrested in Mexico, officials said Wednesday.

Folsom spokeswoman Lt. Cammy Voss said the FBI notified the prison that Glen S. Godwin, 30, was arrested on drug charges in Puerto Vallerta, Mexico.

Godwin had been using the alias of Stewart Carrera, but his identity was confirmed by his fingerprints, Voss said. Godwin was being held in Guadalajara and U.S. authorities are expected to seek his extradition.

Godwin was serving a sentence of 26-years-to-life in prison for first- degree murder when he escaped June 5, 1987, with the help of his wife and a former prisoner, Folsom officials said.

He cut security bars on a storm drain, then used an inflatable rubber raft to cross the American River, which flows past Folsom.

Godwin was convicted of the 1980 murder of a Riverside County man. According to testimony at his trial, Godwin stabbed the man 26 times in an attempt to steal drugs from him.

His escape was the third in nearly two decades at Folsom, prison authorities said.
