In a People magazine exclusive, Bret Powers, who was not only Michael's close friend but also his former college roommate, said Cavallari had been working for his father's real-estate development company.
"He was doing that and doing real well," Powers told People. "Everything seemed to be going well in his life, and I just don't know what caused this. He's a goodhearted guy and he was always someone you could count on if you needed anything... I'm still in shock."
Cavallari's body was found in the Salt Wash, Utah, area after he went missing on November 27. He had been arrested and spent a brief period in jail the day before, and surveillance video captured him in a convenience store, the last known images of him alive.
