DENVER -- Relatives of a Broncos fan who disappeared during last week's game are wondering how a man with no known health or personal problems could seem to vanish without a trace.
Family and friends of Paul Kitterman, 53, have been searching for him since Thursday night's matchup with the San Diego Chargers at Sports Authority Field.
Police said no new information about his whereabouts emerged Tuesday.
Kitterman's stepson, Jarod Tonneson, said he has not been seen since he left his seat to meet friends during halftime. Tonneson filed a missing-persons report with Denver police, scoured the sprawling stadium, called local hospitals and detox centers and taped fliers around the city.
"We just don't know what else to do," Tonneson told The Associated Press on Monday. "Paul is a simple guy, he doesn't like technology, he doesn't get into drama. He's just an easygoing guy."
The two went to the game with two of their friends after a day spent working and hunting at another friend's ranch in Kremmling, a small town in the mountains of northern Colorado.
Kitterman and Tonneson, both construction workers, hurriedly made the 100-mile trip to the stadium after a friend offered tickets. It was Kitterman's first time there. In their haste, Kitterman forgot his cellphone and took no credit cards and very little cash.
Still, Kitterman had memorized his friends' phone numbers and would have found ways to reach out if he wanted to leave. He had four or five beers in the course of a four-hour span -- not enough to become disoriented, Tonneson said.
Denver police spokesman Sonny Jackson said detectives don't suspect foul play, but he would not elaborate. The department was trying to support the family in their search, Jackson said.
"They just don't seem too worried about it, being that he is a grown man," Tonneson said of police. Police said a man's body was found close to Interstate 25 near the stadium on Tuesday but they do not believe it is Kitterman.
His parents live in Arizona and his siblings in Missouri, and Kitterman has few contacts in the Denver area, Tonneson said.
"He wouldn't just take off, you know?" Tonneson said. "He wouldn't leave me there."
