Ian L. Stawicki, the man police say is responsible for killing five in two separate shootings before turning the gun on himself in Seattle Wednesday, owned at least six guns and had a concealed weapons permit that was valid through 2015. Stawicki purchased a .45-caliber handgun in 2008, just after he was cleared of domestic violence charges. It's not clear whether any of those weapons were used in the shooting. Stawicki's family has said he was mentally ill.
