The dispatcher is no longer employed with the department, said Anne Arundel County Fire department spokesman Capt. Russ Davies. The dispatcher's name was not released.
The Feb. 1 incident triggered an investigation after the dispatcher told the girl to stop whining. Officials initially said the dispatcher might return to answering 911 calls but could also face termination, depending on the outcome of the investigation.
Warrick's 13-year-old daughter was in the car with her younger brother and called 911. The teen gave the dispatcher information but struggled to remain calm. She pleaded with the dispatcher to "hurry up'' and send help, but the operator said he needed the exact location of the crash. At one point, the dispatcher interrupted the girl.
"OK, let's stop whining. Let's stop whining, it's hard to understand you,'' he said.
The dispatcher sounded frustrated when the girl asks him to send help quickly. At one point he asked if there's someone else he can talk to.
Warrick was killed in the crash. His fiancée, Julia Pearce, 28, was seriously injured.
After the incident, Davies told The Associated Press the dispatcher should have handled the call differently.
