VIDEO : Did Cold Weather Contribute To The Death Of Kristin Cavallari's Brother?

Authorities in Utah believe prolonged exposure to the elements may have contributed to the death of the brother of reality TV star Kristin Cavallari. Grand County Sheriff Steve White said there were no signs of major trauma on the body believed to be that of Michael Cavallari, which was found in a steep and rocky area near an exit about five miles from where his car was discovered almost two weeks earlier. Michael Cavallari's Honda Civic was discovered on Nov. 27 about 100 feet off of Floy Wash Road, around five miles south of an exit on Interstate 70 in Grand County, the sheriff's office said.
