A suspect is in custody after a mass shooting inside a downtown Orlando high-rise left one person dead and five others injured, according to Orlando police.

**Updated at 7:02 p.m.**
Police say 40-year-old Jason Rodriguez was arrested at his mother's home after he opened fire in a downtown Orlando office building.

Officials say Rodriguez entered the high rise building where he was fired two years ago. An eye witness said she and other employees huddled in a corner until police arrived.

Ambulances converged on the scene. Emergency responders began a floor-by-floor search for the gunman and the victims.

A nearby elementary school and a high school were placed on lock down, with police officers carrying high-powered rifles surrounding the buildings.

Police are still trying to determine a motive for the shooting. Reports indicate Rodriguez may have recently filed for bankruptcy.
