The gunman remains on the loose.
Freelance journalist Bradley Rayford was nearby when the shooting occurred.
“As we were about to pack our cameras up, we hear what we thought were fireworks up the street,” Rayford told ABC News. “Turns out, happened three more times. It was gunfire because we saw the muzzle fire from the gun up top of the street.
“It was kind of traumatic. ... I'm still kind of in shock because of it.”
The shooting and its aftermath were captured on social media and streaming video, tense moments experienced in real-time.
