The best friend of a man who went missing during halftime at a Denver Broncos game went “On The Record” tonight.

Paul Kitterman, 53, went missing during halftime of a Broncos-Chargers game.

“I believe that he is somewhere in that stadium, that he never left,” his friend, Brian Case, told Greta Van Susteren tonight.

Case said he spoke to Kitterman just two days ago. He said Kitterman’s life was fine, and he was happy.

Case urged authorities to search every corridor of Sports Authority Field at Mile High. He also said he told police that he would have 100 people down at the stadium to search tonight, if authorities would allow it.

Anyone with information on Kitterman is urged to call the tip line at 720-913-2000.
