NFL QB Jay Cutler's brother-in-law found dead after being reported missing

Michael Cavallari, the brother of former "The Hills" star Kristin Cavallari, has been found dead after going missing, Kristin said in a statement Thursday.

"We want to thank everyone for their love, support and prayers during this very difficult time. We have just been informed by the authorities my brother's body has been found," Cavallari said in a statement to People. "This is a very painful time and we are still processing it all. We kindly ask everyone please respect our privacy during our time of grieving."

On Monday, news broke that Michael Cavallari had been missing for 10 days under "suspicious" circumstances.

Utah law enforcement were first called in about Michael Cavallari's disappearance on Nov. 27, when it received a report about an abandoned 2014 Honda Civic which appeared to have veered into a ditch 100 feet off Interstate 70.

Credit card receipts in the vehicle led police to a convenience store in Monticello, Utah where the 30-year-old, who is the brother-in-law of Chicago Bears quarterback Jay Cutler, was seen on security footage.

Earlier this week, Cavallari thanked fans for their support via Instagram, saying that she remained "hopeful" for his return.

"I appreciate all the concern, thoughts, and prayers that have been extended to me and my family. We remain hopeful and I will share any news that we receive. I have such gratitude for all those that have shared their support."
