ST PAUL, Minn. — St. Paul Police opened a homicide investigation after a man's body was found inside his home Monday.

Squads were dispatched just before 5 p.m. after a 911 call from someone reporting an assault on the 1700 block of Benson Ave. When police entered the home they found 33-year-old Matthew Richard Schramm unresponsive. Officers immediately called for St. Paul Fire paramedics, but Schramm was soon declared dead on the scene.

Homicide investigators interviewed a number of people who knew the victim, including the 911 caller who was taken down to police headquarters for questioning. Police found that man had warrants out for his arrest and he was taken into custody.

Crime lab technicians spent Monday and Tuesday processing the scene for evidence that could indicate what Schramm was doing in the hours before his death, and exactly how he died. 

A police spokesman says in the past year they have received and responded to 30 to 35 calls regarding the address where Schrammm was found dead. Those calls range from disturbances to suspicious activity. 

The death is being pursued as the seventh homicide this year in St. Paul.

A full autopsy report is expected from the Ramsey County Medical Examiner's Office. 

No arrests have been made in relation to this case.
