Utah authorities say a body believed to be that of NFL quarterback Jay Cutler's brother-in-law has been found in southern Utah, nearly two weeks after his car was abandoned.

The Grand County Sheriff's office said that crews Thursday morning discovered the remains believed to be that of Michael Cavallari, the brother of reality TV personality Kristin Cavallari.

Messages to Kristin Cavallari's publicist were not immediately returned Thursday.

Authorities have been searching for Michael Cavallari since his car was found with the engine running, and the air bag deployed, in a remote part of Utah on Nov. 27.

Investigators believed he was just passing through Utah.

Michael Cavallari had been arrested in California four days before his car was found on allegations that he acted threateningly toward a woman and had a gun.
