WBRZ - Baton Rouge

Update: Police in Orlando say a gunman has been apprehended after killing one person and injuring five others at a downtown office building where he was let go two years ago.

Police Chief Val Demings said 40-year-old Jason Rodriguez surrendered to police at his mother's home after officers saw him through a window and asked him to come out.

Asked by a reporter outside the police station why he did it, he replied: "Because they left me to rot."

Demings confirmed that one person was killed in the shooting at the Legion Place office building downtown. Five others were hurt.

Gerry Gilgo, who works on the floor where the shooting occurred, told The Associated Press she was meeting a co-worker at the elevators for lunch.

"She yelled there are gun shots! There are gun shots! Get back in your office," Gilgo said.

Witnesses told police the shooting started at Reynolds Smith & Hill, a transportation engineering consulting firm in the building.

Company spokesman Mike Bernof told CNN all the people shot were in the firm's office. He could not say if any died.

Rodriguez, an engineer, was released in June 2007 for performance issues, Bernof said. He could not say why.

The firm performs transportation engineering work with the Florida Department of Transportation.
