LOS ANGELES (AP) — Investigators believe a homeless man killed his wife in an abandoned restaurant, chopped up her body, stuffed it into a suitcase and then calmly rode with it aboard a train before he burned her remains in a parking lot, Los Angeles police said Tuesday. After Valentino Gutierrez killed his wife last week in a shuttered restaurant in Pasadena, he dismembered her body, stuffed her remains into a large suitcase and boarded a light-rail train at a nearby station, Deputy Chief Justin Eisenberg said. Gutierrez, 56, who was charged Thursday with murder and arson, didn't draw any suspicion on the train and hopped aboard his bicycle after he exited the train.
