TV personality Kristen Cavallari's brother Michael's death may have been caused by prolonged exposure to the elements, authorities in Utah have said.
Michael's body was found on Thursday, two weeks after he had first gone missing, reported E! Online.
Grand County Sheriff Steven White said that frigid weather in the area might have played a factor in his death.
Nighttime temperatures were said to be at or below freezing in the area around the time his car was found against a small embankment.
"There were no signs of major trauma and no suicide note. Cops did not find any evidence of drugs or alcohol either," officials said.
The official cause of death is still pending toxicology reports, which are expected to be released in the next 6-8 weeks.
On Instagram, Cavallari posted a tribute to her brother, sharing a picture of the two siblings as children. "My heart is in a million pieces. Mikey, I could always count on you to make me laugh. 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," Cavallari wrote.
