Prior Struggles with Mental Health and the Law

Tragically, Michael's life was marred by ongoing struggles with mental illness and substance abuse. These issues led to several encounters with law enforcement in the years leading up to his disappearance. Days before he vanished in Utah, Michael was arrested in Orange County, California, on November 23, 2015, and held in jail on charges of making threats. He was released shortly before embarking on the fateful journey that led him to the remote desert of Utah. Kristin Cavallari later speculated that her brother may have been suffering from bipolar disorder.

The Timeline of a Tragic Disappearance in the Utah Desert

The two-week period between Michael’s car being discovered and his body being found was a frantic, high-profile search that involved multiple agencies and intense media scrutiny.

November 27, 2015: The Abandoned Vehicle

The official search began on November 27, 2015, the day after Thanksgiving. Police discovered Michael’s 2014 Honda Civic abandoned in a remote area of Grand County, Utah. The car was found approximately 100 feet off Floy Wash Road, about five miles south of Interstate 70 (I-70). The engine was still running, and the airbags had been deployed, suggesting a minor traffic accident had occurred. Crucially, Michael was nowhere to be found. His laptop and cell phone were inside the vehicle, but his wallet was missing. The location where the vehicle was found is a desolate, rugged expanse of the Utah desert, known for its steep and rocky terrain. The Grand County Sheriff’s Office immediately launched a search operation, utilizing helicopters, search dogs, and ground crews to scour the vast, unforgiving landscape.

Two Weeks of Uncertainty and Public Plea

As the days turned into a week, the search efforts intensified. Kristin Cavallari, who had just given birth to her daughter Saylor James Cutler, flew to Utah to be close to the search efforts. She publicly issued a heartbreaking statement, pleading for information and expressing her deep worry for her older brother. The involvement of a high-profile figure like Kristin, along with her then-husband, NFL quarterback Jay Cutler, brought significant national attention to the missing person case.

December 10, 2015: The Discovery and Official Ruling

The search came to a tragic end on December 10, 2015, when Michael’s body was discovered. His remains were located in the Salt Wash area, approximately three miles from where his abandoned car was found. The terrain was described by the Grand County Sheriff’s Office as extremely difficult to navigate. The Utah State Medical Examiner’s Office conducted an autopsy and officially ruled Michael Cavallari’s death as an accident. The cause of death was determined to be hypothermia from prolonged exposure to cold temperatures. Investigators confirmed that there was no evidence of foul play, suicide, or the use of drugs or alcohol at the scene, indicating that his death was a pure tragedy resulting from getting lost in the harsh, cold desert environment.
