Police on Sunday were looking for the people who killed a man and left his body in a parking lot in St. Paul.

Someone flagged down officers on patrol shortly after midnight near Arlington Avenue E. and Arkwright Street N. about a body in the parking lot of the Arlington Arkwright Dog Park just east of Interstate 35E on the city’s East Side. No arrests have been announced.

St. Paul Fire Department medics arrived and declared the man dead at the scene. His identity and what led to his death remain undetermined, police said.

However, an officer at the scene was heard over emergency dispatch audio saying the man was middle-aged, and it’s “looking like a possible gunshot wound to the head” killed him.

One officer also reported to dispatch that the man apparently was dumped there, pointing out that a “vehicle pulled in here ... pulled out [and] there’s tire tracks going southbound on Arkwright.”

The suspected vehicle was occupied by four males, the dispatch audio said.

In the meantime, homicide investigators were looking for witnesses, and police forensics experts were going over physical evidence.

Anyone with any information about the case is urged to call police at 651-291-1111.

This is the 17th homicide in St. Paul this year.
