AS police continue their search for Kristin Cavallari’s brother, new reports have emerged about his wayward past.
Michael Cavallari vanished 12 days ago in the Utah desert after his car was found abandoned on a remote dirt road with its engine running and the air bag deployed.
Now sources close to the family told Daily Mail Online the 30-year-old is a jobless alcoholic, who has been arrested multiple times.
Just days before he disappeared he was arrested on Nov. 23 and briefly held in an Orange County jail for making criminal threats against a woman – the same day his famous sister Kristin gave birth to her daughter Saylor.
The unnamed woman told police Cavallari had appeared outside her home carrying a shotgun after they had argued.
And sources close to the family also told Daily Mail Online how his issues with alcohol made him a ‘difficult’ and ‘crazy’ character.
Troubled Cavallari is believed to have spent his days drinking, smoking and playing online poker inside his father’s $6.6million home in San Clemente, California, where he lived.
But several months ago, dad Dennis, 63, is thought to have kicked him out after growing tired of his son’s erratic behavior.
Cavallari was previously arrested for DUI in November 2014 and received three years probation.
It certainly seems his life is world’s apart from his little sister’s.
Kristin, 28, shot to fame as a teenager on MTV reality show Laguna Beach and later appeared on spin-off show The Hills.
She is now married to Chicago Bears quarterback Jay Cutler and is mom to three children under the age of three; Camden, Jaxon and daughter Saylor.
