DALLAS It started with a bang... and a shattered window.
A Dallas firefighter was sitting in a ladder truck traveling down R.L. Thornton Freeway on April 12 when the window next to him exploded just after a loud noise.
According to a Dallas police report, further investigation showed that the fire truck was hit by a bullet fired by an unknown suspect.
Dallas police initially sent a news release saying their crime scene response investigators found no evidence of a bullet or a projectile, and were unable confirm the truck had been shot at.
But sources said investigators believe the window was shot out.
The case is filed as an aggravated assault on a public servant.
Those firefighters work out of Station No. 19. Not far away, firefighters at Station No. 24 were threatened two weeks earlier.
According to a March 22 police report, a firefighter answered a couple of calls on the station's private line. The suspect became agitated over the phone and started using profanity, the report said.
The suspect then yelled, Are you ready to die? Are you ready to die?
Fire Station No. 24 was evacuated and employees were sent to another location.
Dallas police tried to trace the caller, but it had already been disconnected.
A Dallas Fire-Rescue spokesman said the agency could not comment at this time.
Dallas police are still trying to determine whether someone targeted the firefighters.
