Jury returns guilty verdict for man in slaying of ex-wife whose 911 call was mishandled

DALLAS – Jurors have found a Dallas man guilty of murder in the death of his ex-wife whose 911 call was mishandled by Dallas police.

A Dallas County jury deliberated about 3½ hours before finding Delvecchio Patrick guilty of killing Deanna Cook at her home in August 2012. Jurors could sentence Patrick to up to life in prison.

Police say Patrick was attacking Cook when she called 911 with her cellphone, but the operator didn't get an address. It took about nine minutes to find Cook's address, after which dispatchers sent officers to Cook's home. Officers knocked on the door, then asked for someone to call Cook back. The call went to voicemail. Officers also looked through windows of the home and saw nothing. Two days later, her family found her body.
