SALT LAKE CITY, Utah -- Michael Cavallari, brother of reality star Kristin Cavallari, was found dead in Utah.

Kristin Cavallari told E! News that her brother's body was found. Michael Cavallari, 30, was reported missing two weeks ago.

"We want to thank everyone for their love, support and prayers during this very difficult time," Kristin Cavallari said in a statement to E! News.

On November 25, Michael Cavallari bonded out of jail after allegedly threatening a woman in Orange County, California. The unnamed woman told deputies the two argued days earlier and she was afraid because he kept returning to her apartment.
