"I just heard like 40 shots, just continuous shots, and people were scattering around," one witness, Zack, said. "I couldn't believe it. Everybody was startled."
Zack, wearing a T-shirt with the words "HANDS UP GUNS DOWN," told News4 he was with his family and about to get a haircut at a barber shop in the shopping center when he heard the gunfire.

"It's a lot of work to do out here in the streets, you know," he said. "And a lot of young lives is getting lost. It's just senseless, so we gotta stay in front of it."
Bullets also hit several vehicles and businesses, including the barber shop Zack planned to go to, authorities said.
Another man said he rushed to the shopping center after hearing about the shooting.
"For somebody to just open fire in this parking lot - it's wrong," he said. "My friends work in that barber shop. I grew up with these guys. These guys are my friends, they keep me looking good, and I know they're scared. I know they're worried."
No suspects were immediately in custody. Police have not yet said what led up to the shooting.
"[It's] disheartening. It happens all around the country, and now it's come here. People are so quick to pick up a gun, and it's wrong," the man who rushed to the shopping center said.
