The 911 operator charged with hanging up on emergency callers because she didn't want to talk apparently disconnected hundreds of calls, a prosecutor said Monday.

Crenshanda Williams, 43, appeared in court Monday on two misdemeanor charges for interference with emergency telephone calls.

Williams, who can be heard saying, "Ain't nobody got time for this," while hanging up on one caller, told Houston police she hung up on callers because "she did not want to talk to anyone at that time," according to court documents.

Prosecutor Claire Morneau, with the Harris County District's Attorney's Office public integrity unit, said investigators have identified about 825 calls in which Williams hung up and the person called back within five minutes.

Morneau said that they had spoken to two individuals Williams had hung up on in March, including one who was reporting a robbery at a convenience store and another caller who was reporting cars racing on a freeway.

"Since the case has been filed more people have called and of course we will be following up with those individuals," Morneau said.

Williams could face additional charges if prosecutors are able to speak with more callers, identify the emergency the caller was reporting and confirm the 911 operator hung up on them, Morneau said.

Williams, who was fired from the Houston Emergency Center, left the court room wearing a black hoodie, trying to hide her face. She declined to speak with reporters. Her attorney, Abel Izaguirre, also declined to comment.

If convicted, Williams could receive up to one year in jail for each misdemeanor charge. She is set to appear in court again Nov. 10.
