There were two outside hired shooters involved in the massacre using Tompson submachine guns and the two police officers that came into the warehouse first and lined the seven Northside gang members against the wall. Between the seven bodies there were 150 bullets and a total of 200 were fired so there should be bullet holes in the wall. Some of the bodies were almost cut in half by the machine gun fire and there were guts all over the place. Very gruesome! Just saw this on the History channel.
