The husband of the secretary to a priest who was beaten to death was booked for investigation of the priest’s murder, Santa Cruz authorities said. Cab driver Edward Bowman, 39, was arrested at his home in the death of Father John Karastamatis, a Greek Orthodox priest, Police Chief Jack Bassett said. A local judge ordered the arrest warrant sealed until a court hearing. Karastamatis, 47, was killed last May 19 by repeated blows from a blunt object. He also was stabbed, and his wallet and keys were taken, detectives said. Bowman’s wife, Anna, 43, shot and killed herself Dec. 19 after firing at a detective who wanted to question her about the slaying. Bassett said Anna Bowman also would have been arrested if she had not committed suicide. Anna Bowman had worked for Karastamatis as a volunteer secretary. The priest had “taken the Bowmans under his wing,” Lt. Mike Dunbaugh said.
