From what I'm understanding here (I'm quickly reading before I have to drive) that a man has been arrested for this, victim has not been named but his SO is missing.
Here's an LA Times article with more details about the body found burned in Cypress Park. It's a horrific crime. The police say that the man killed his wife in an abandoned Pasadena restaurant, dismembered her, and transported her body in a suitcase on the Gold Line and via bicycle to the Cypress Park Home Depot parking lot, where he set fire to the suitcase and body.
