Witness describes panic, injured victims after Tucson mass shooting

"All I heard was the gunshots and then everybody got down," DeWitt said. 

"I just kind of fell on the ground, and then like crawled my way to the metal table" on the patio.

While hiding under the table, he was next to someone who was shot and bleeding, he said. 

"The girl next to me, she was bleeding out of her legs and screaming for someone to help." 

The two friends DeWitt was with pounded on the glass window from inside Empire to get his attention.

"She was knocking on the window, and she was waving her hands. So, I went inside, but I slipped, and then that's when we ran. We officially got inside and then ran for somewhere to hide," he said. 

They locked themselves inside the bathroom. 

"Then a girl was pounding on the door, saying 'f---ing open the door,' and then we opened the door, and she was covered in blood." 

Shortly after they opened the bathroom door, police arrived and started helping the woman.  

DeWitt and his friends, who were not injured, went to the kitchen in the back to get away from the scene. 

He spoke with two police officers in the kitchen.

"They wanted me to stay and talk to the detective, but I gave them my number because I was feeling overwhelmed and nauseous," he said. "So I left through the back because there was too much blood and two people laying down in the front."  

On its Instagram account, Empire Pizza said two of the mass shooting's nine victims were on its patio at 137 E. Congress when bullets came from outside.

Police said the gunfire broke out in a confrontation between two groups. The nine injured people were taken to a hospital, initially in critical condition, police said.  

A suspect who was seen running from the area, later identified as David LeRoy French, 21, was shot and injured by a Tucson Police officer who was in the area patrolling and ran to the scene. French was arrested and faces nine counts of aggravated assault with a firearm, nine counts of aggravated assault, and discharging a firearm at a structure, court records show.
