NFL fan disappeared at halftime of Denver Broncos game

DENVER, Colo. -- Friends and family of a man who disappeared during last week's Denver Broncos' NFL game are asking the public for help finding him.

They say 53-year-old Paul Kitterman of Kremmling, Colo. was last seen leaving his seat at halftime during Thursday night's Denver-San Diego game at Sports Authority Field.

He was at the game with his son, friend Tia Bakke and Bakke's boyfriend.

Bakke told KUSA-TV, a local NBC affiliate, that Kitterman is loyal and responsible and he would never leave people wondering where he was, especially not his son. She says Kitterman rode with them to the game and didn't have a cell phone or credit cards with him.

Described as a white male with brown hair and hazel eyes, weighing about 190 pounds, he was wearing a dark-colored hoodie and a Broncos cap when he disappeared, according to a flier from the Denver Police Department.

A police spokesman told 48 Hours' Crimesider police have helped the family create a flier and have taken a police report, but said there's no apparent criminal element to the disappearance.

"We don't have a criminal nexus to this right now," Denver Police spokesman Sonny Jackson told Crimesider.

Anyone with information about Kitterman's disappearance should call Denver police at 720-913-2000.
