DALLAS (AP) — Relatives of a Dallas woman who called 911 but was later found slain in her bathtub have met with police Chief David Brown.

The Dallas Morning News (dallasne.ws/PkG4iU) reports Brown met privately Monday with Deanna Cook's mother and two sisters at police headquarters. All later declined comment.

Cook's ex-husband, Delvecchio Patrick, has been charged with killing her and remains in custody.

Brown has said a 911 operator mishandled Cook's Aug. 17 call by not relaying that her life appeared to be in danger. Two officers went to Cook's house but left when nobody answered the door.

Her family discovered her body Aug. 19.

Police last week updated procedures to require officers to use flashing lights and sirens on calls where the victim is in danger of serious injury or death.
