Records show that Eduardo Sencion had no criminal record, not even a traffic ticket. Family members say Sencion was mentally troubled, but no other details were given. Police are examining the gun to determine if it was automatic or semi-automatic. Sencion used 30 round clips and reloaded at least once. Police found a handgun and another assault rifle in Sencion's van. Ralph Swagler, the owner of the other restaurant in the shopping center, said when he heard Sencion start shooting he went to grab his own weapon but decided against engaging Sencion in a gun battle. "I had my pistol; I wasn't going up against an automatic rifle," he said. "I'm sorry. I wish I would have shot him in the back now as he was going toward IHOP, but I wasn't clear on the situation. When he came at me, when somebody is pointing an automatic weapon at you - you can't believe the firepower, the kind of rounds coming out of that weapon."
Six of the seven people wounded remain hospitalized with severe injuries. Police still don't have a motive for the shooting.
