A man is in the hospital with possible life-threatening injuries after being shot Monday morning in an apartment building on St. Paul's East Side.

Police went to the building on Westminster Street near Geranium Avenue in the Payne-Phalen neighborhood about 3 a.m., said police spokesman Sgt. Mike Ernster.

The victim was taken to Regions Hospital, Ernster said.

Officers searched the area for a suspect, but have not found the gunman.

"We do not believe this is a random incident," Ernster said.

The incident, which drew a large police presence, remains under investigation, he said.
