Dallas police said Tuesday that the operator who took a 911 call from a woman who was found dead in her home two days later has stepped down.
Deanna Cook called 911 on Aug. 17 and said her former husband was attacking her. Two officers went to her home and knocked on her door but no one responded. They left after looking in the windows.
Cook's family found her body two days later after forcing their way into her home.
The Dallas Police Department oversees the 911 call center.
An internal police investigation found that Tonyita Hopkins, the operator who took the Aug. 17 call, failed to enter the proper information into the call sheet. Police said the sense of urgency was not conveyed to officers.
The department would not comment on the circumstances of Hopkins' resignation.
Hopkins' family has released a statement on her behalf.

"For legal reasons, we have been advised not to speak publicly but, when the time is right, we would love to share our side of the story," the statement said.
"Hopefully, she resigned for a reason," said Karletha Gundy, Cook's sister. "That could give us closure."
Gundy and Cook's daughters were among the relatives who discovered her body two days after she was killed.
"My nieces are still grieving," Gundy said. "They miss their mom, just trying to make it."
Cook's former husband, Delvecchio Patrick, is charged in her slaying.
Cook's relatives have filed a federal lawsuit against Hopkins and the city.
The family called 911 on Aug. 19 to report that Cook was missing and request that an officer check her home. The call-taker, Angelia Herod-Graham, told family members to contact the jail and local hospitals.
Herod-Graham was terminated. Police said she previously mishandled two other calls.
