Jay Cutler's brother-in-law arrested with shotgun before going missing

Investigators on Monday were trying to piece together what happened to NFL quarterback Jay Cutler's brother-in-law, whose abandoned car was found more than a week ago with its engine on and the air bag deployed near a remote dirt road in Utah.
Police documents show Michael Cavallari, 30, was arrested outside a city hall in southern California with a loaded shotgun four days before his car was found abandoned in Utah.
The documents reveal that Michael Cavallari was arrested on Nov. 23 after a woman called the Orange County Sheriff's department to say he had been outside her apartment with a shotgun.
The unnamed woman told deputies the two had argued days earlier and she was afraid because he kept returning to her apartment.
