Michael was discovered to be missing on Friday, November 27 - the day after Thanksgiving - when his car was found crashed and abandoned off a southeastern Utah interstate.
It's believed that Cavallari was on a cross-country road trip from his home in California to Illinois, where his sister and her husband, Chicago Bears quarterback Jay Cutler, live.
Just four days prior to the mysterious crash, Kirstin Cavallari gave birth to her third child with Cutler, a daughter named Saylor.
KSL reported that The Grand County Sheriff's Office received a report on November 27 that a small passenger car could be seen about 100 feet from the Floy Wash Road, five miles from exit 175 on the freeway between Green River and Crescent Junction.

Police say Mr Cavallari's car hit a rock on the side of the road and then crashed.
The vehicle was found running and the airbag deployed. Cavallari's laptop and cell phone were inside.
'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.'
Police identified the car as Michael Cavallari's from credit card receipts that led to the convenience store in Monticello where they saw him in footage on the store's security system (above)
