The Dallas Police Department is investigating its response to a woman who was found dead two days after calling 911 to report she was being attacked.
Deanna Cook, 32, was found dead in her bathtub on Sunday by family and friends who had grown worried. On Friday, Cook called 911 from her cell phone at 10:54 a.m. and could be heard yelling, "Delvecchio, why are you doing this?"
