The two men shot to death in St. Paul were good friends who went to high school together, a brother of one of the men said Wednesday. The two were shot to death about a mile apart, and authorities on Wednesday were trying to determine whether the killings were related. Both men were found outside, and no arrests have been made. One man was found shot about 11:30 p.m. Tuesday in the 800 block of Fuller Avenue, said police spokesman Sgt. Paul Paulos. The man died at Regions Hospital. Shortly after 8 a.m. Wednesday, another man was found shot in the 400 block of Charles Avenue, Paulos said. That man was dead at the scene.
