Friends and family of a Colorado man are asking for the public’s help in finding the man after he disappeared from last Thursday’s Denver Broncos game.

Family members say 53-year-old Paul Kitterman of Kremmling was at the game with his son and two friends, and was last seen leaving his seat at halftime during Thursday night's Denver-San Diego game at Sports Authority Field.

One of the friends, Tia Bakke, told KUSA-TV that Kitterman would never leave people wondering where he was, especially not his son. Family and friends also say Kitterman doesn’t have a cell phone, and was only carrying about $50 in cash.

Family also says that Kitterman does not have any medical problems or issues with drugs or alcohol.

Anyone with information about Kitterman's whereabouts are asked to contact the Denver Police.
