Kristin Cavallari's brother 'died from cold temperature'

Kristin Cavallari's brother is suspected to have died from cold temperatures.

Michael Cavallari - the 30-year-old elder brother of the 'Hills' star - was confirmed dead on Thursday (11.12.15), having been missing for almost two weeks, and law enforcement officers have now reportedly revealed that he most probably passed away after he was left exposed to the elements.

There were no signs of trauma and police didn't discover drugs or alcohol where his body was found, according to TMZ, which reports that law enforcement officers are of the belief it was the cold temperatures that ultimately killed Michael.

However, the Grand County Sheriff's Office has still to officially confirm the cause of death.

In a statement released yesterday, the office said: "At approximately 10:30 a.m. search crews located remains believed to be that of Michael Cavallari.

"At this time, the body is being transported to the Office of the Utah Medical Examiner for positive identification and to determine the cause of death.

"The search crews were searching the Salt Wash area, near exit 175 on I-70 in Grand County. The terrain where the body was located is a steep and very rocky area."
