The Denver Police Department on Tuesday investigated a death on the east side of Interstate 25 near Sports Authority Field.

The body of a man was found near the intersection of West 3rd Avenue and Walnut Street, said Sonny Jackson, a police department spokesman. The circumstances surrounding the man’s death are under investigation.

It is too early to determine whether the body is that of Paul Kitterman, a 53-year-old man who disappeared during Thursday night’s Broncos game. However, Jackson said it does not appear to be Kitterman.

Kitterman of Kremmling was last seen at halftime. His family filed a missing person report and has been searching the area around the stadium for him.
