 Margaret trying to determine right now, FBI also searching the home, trying to figure out if there were other weapons there. Also trying to determine if this was his weapon. No positive confirmation of that at this time. Still a lot of lingering questions about how he was able to procure this semi-automatic weapon. We do know that based on how this weapon works, it wouldn't have been an automatic sort of fire. He had to pull the trigger, pull the trigger, pull the trigger again, six to eight rounds.
