by at . Comments

Late last month, reality star Kristin Cavallari's brother, Michael Cavallari, disappeared following a run-in with police.

Sadly, Michael's body was found by authorities in a Utah desert yesterday. He had been missing for two weeks, and the cause of his death was not immediately apparent.

Now, TMZ is reporting that investigators have determined what killed Cavallari, and his passing was not brought about by drugs or alcohol, as several media outlets previously reported.

The website claims that Cavallari was killed by exposure and hypothermia.

Temperatures in that part of the state dipped into the low teens several times over the past week, and it is not yet known how long Cavallari endured the elements before his body gave in.

Police say no drugs or alcohol were found on the scene.

Friends and family feared the worst after the 30-year-old's car was found abandoned on a Utah highway with the motor still running.

Just before his disappearance, Cavallari was arrested after allegedly threatening an unidentified woman with a gun.

He fled Los Angeles shortly after being released from police custody.

Kristin, who starred on the MTV series Laguna Beach and is the wife of Chicago bears quarterback Jay Cutler paid heartbreaking tribute to her late brother on Instagram page last night:

"My heart is in a million pieces Mikey, I could always count on you to make me laugh," Kristin wrote.

"You had such a good heart and will be forever missed. I'm at a loss for words but I know u are in a better place and finally at peace. I love u so much RIP."

We'll have further updates on this story as more information becomes available.
