Michael Cavallari, the brother of former "The Hills" star Kristin Cavallari and brother-in-law of Chicago Bears quarterback Jay Cutler, likely died at least in part due to exposure to the elements, a spokesman for the Grand County, Utah, Sheriff's Department told TheWrap on Friday.

The spokesman said that law enforcement believes that exposure to the elements was a "contributing factor" in Cavallari's death.

Currently there is no evidence that Cavallari committed suicide, or that drugs or alcohol played a part in his death, the spokesman added. However, he noted, the cause of death will not be known until the medical examiner completes an investigation.

The Utah Medical Examiner had no comment for TheWrap on Cavallari's case.
