FOX59 has also confirmed the identity of the gunman as Johnathan Douglas Sapirman, 20, of Greenwood. Sapirman reportedly entered the mall with a rifle and several magazines. He shot and killed three people before an armed citizen killed Sapirman.

According to police, Sapirman doesn’t drive and walked to the mall. Sapirman was armed with a Sig Sauer M400 semi-automatic rifle along with another rifle and a pistol. He had more than 100 rounds of ammunition with him, authorities said.

According to authorities, Pedro and Rosa were sitting and eating when Sapirman opened fire and shot them. Gomez was outside the restroom when he was shot.

Family members told police they were surprised by Sapirman’s attack and that he’d never shown violent indications to them. Sapirman lived alone and when police searched his apartment they found a burned laptop in the oven. His cell phone was found in the mall’s bathroom toilet.

Police said 24 rounds were fired and five people were hit before Dicken shot and killed Sapirman.
