TMZ: Authorities say Kristin Cavallari’s brother died from exposure to the

You had such a good heart and will be forever missed. Very, very hostile conditions for somebody that was not properly equipped to be here, could be fatal, “said Grand County, Utah Sheriff Steven White”.

Kristin Cavallari is paying tribute to her late brother, Michael Cavallari.

Michael Cavallari had been missing for almost two weeks.

White also added that the Medical Examiner will determine the time and cause of death of Kristin Cavallari’s brother while toxicology results may take up to 8 weeks for the results to come back, Daily Mail has learned.

“I’m at a loss for words, but I know u are in a better place and finally at peace”, she wrote.

Michael Cavallari, the brother-in-law of Chicago Bears quarterback Jay Cutler, was found dead in Utah, according to published reports.

Concerns were raised about Michael’s wellbeing when his auto was found abandoned on a road in Utah with the engine still running. “The terrain where the body was located is a steep and very rocky area”.

Medical examiner officials were not immediately available for comment Friday. The clerk at the Maverick store said Michael had purchased gas and asked for directions to Salt Lake City before getting on the 191 north. The police searched the area near and around the Michael’s auto, but were not able to find the driver at the time.

On Monday, Kristin Cavallari posted a photo on Instagram of her and her brother as children with a message thanking people for their thoughts and prayers.

Evidence shows Michael Cavallari’s 2014 Honda Civic hit a couple of big rocks and washes, likely causing the air bag to deploy, White said.

His cellphone and laptop were inside the vehicle, but there was no blood or any other sign of foul play. Authorities discovered Michael Cavallari’s body only a few miles from the vehicle he had abandoned in a ditch off the I-70 highway in Utah. He bailed out of jail November 25.

On Thursday, Kristin Cavallari was spotted for the first time since news of her brother Michael’s death. They have three children together.
