The latest on the Chattanooga shooting (all times local):

1 p.m.

A woman who says she witnessed the shooting in Chattanooga says she heard a barrage of gunfire near one of the shooting sites.

"It was rapid fire, like pow pow pow pow, so quickly. The next thing I knew there were police cars coming from every direction," said Marilyn Hutcheson, who works at a Binswanger Glass.

Chattanooga Mayor Andy Berke said at a brief news conference that police were pursuing an active shooter and there was an officer down.

Hutcheson says she ran inside, where she remains with other employees and a customer. The gunfire continued with occasional bursts she estimated for 20 minutes.

"We're apprehensive," Hutcheson said. "Not knowing what transpired, if it was a grievance or terroristic related, we just don't know."
