As previously reported, Michael was found dead at the age of 30 in Utah on December 10, just three days after he was first reported missing. According to the Grand Sheriff's Department, his body was located in a "steep and very rocky area" near the I-70. His 2014 Honda Civic was abandoned three miles away on a highway in Grand County. On December 11, Grand County Sheriff Steven White told Us that the cold temperature was most likely a "contributing factor" to Michael's death.
The mom of three thanked fans for their support following the tragic news. "My heart is in a million pieces. Mikey, I could always count on you to make me laugh," she captioned a throwback Instagram photo of the siblings on December 10. "You had such a good heart and will be forever missed. I'm at a loss for words but I know u are in a better place and finally at peace. I love u so much RIP."
