ORLANDO (CBSDFW/AP) – Orange County Sheriff Jerry Demings says the five people who died after a workplace shooting at a business near Orlando were shot in several locations in the building.

The shooting occurred around 8:00 a.m. Monday morning in an industrial area of Orlando.

Demings says the people who came to work at the awing manufacturing company “were going about their business” when the shooter started firing.

He says about 12 people were at the company and seven people survived. He says no survivors were shot or hurt.

The gunman, described as a 45-year-old disgruntled former worker, also shot and killed himself.

Several roads in Orlando were closed as deputies responded to the shooting.
