Patrick is accused of beating, choking then drowning Deanna Cook in her bathtub in August 2012. In an 11 minute long 911 tape obtained by News 8, Cook is heard begging for her life and naming her attacker.

She says, 'I'm not doing anything. Baby, please.' Her attacker responds, 'I'll kill you. I'll kill you.'

The case received national attention because it was botched by the police department and a 911 operator. The call was not prioritized, meaning it took an officer 50 minutes to get to Cook's home in the Rylie area of Southeast Dallas
