DALLAS — The family of a Dallas woman found dead two days after she tried to call 911 during a deadly attack filed a civil rights lawsuit against the police Wednesday.

Deanna Cook called 911 on Aug. 17 to report that her former husband was assaulting her. Police have acknowledged the call was not logged correctly so the officers did not know it was an emergency. The two officers who went to Cook’s south Dallas home received no response at the door and left without entering, police said.

Cook was found dead in her bathtub on Aug. 19 after relatives forced their way into the home. The former husband, Delvecchio Patrick, is charged with murder.

Police fired one call taker who told worried family members searching for Cook on Aug. 19 to call the jail and local hospitals first. The call taker who received Cook’s original call was suspended for 10 days.

Police said they have also made changes to how calls are logged, and the department will hire more call takers.

The federal lawsuit alleges police were late responding to the call and relied on officers who didn’t properly investigate.

Cook’s family said Wednesday that police have refused to let them hear the tape of Cook’s call. Police have also declined to release a transcript.
