Vanished! Kristin Cavallari’s Brother Reported Missing — Chilling Details Exposed

Officials said that the last record of the reality star’s brother — a San Clemente, California native — is a gas station surveillance tape filmed Nov. 27. Michael was seen wearing a green sweatshirt and jeans, and is described as a 5-foot 11-inch slender man with brown hair and a beard.

His 2014 Honda Civic was found in Monticello, Utah, according to officials, who were able to recover Michael's computer and phone from the car.

The Civic was off of Interstate 70, and was damaged as the result of collision with a rock, according to Grand County Sheriff Steven White. He noted that the airbag was not out, and the motor was still running.

“We’re combing the area for anything we can find,” White told KSL. “We’re deeming it suspicious, but there’s nothing to indicate anything one way or another. The vehicle was just abandoned.”

Kristin has not released any information about Michael's disappearance.
