(Scroll down for video) A woman called 911 to report that her former husband was trying to kill her, but responding police officers came to the house and when no one answered the door, they left.

Dallas police are now investigating why it took two days to find the body of a murdered woman who had called 911 for help when she was attacked in her home.

Deanna Cook, 32, was on her cell phone with 911 for 11 minutes when she was murdered. Police said they responded to her home after about nine minutes, the time it took to find her address.

Once there, they knocked on the door and not getting any answer at the door or on the phone, they left. Cook’s body was found in the bathroom, on Sunday by her teen daughter, who had helped other family members burst into the home after she did come to church. Cook’s, former husband, Patrick Delvecchio, has been charged with her murder.

Police refused to release the 911 call transcript, but the local newspaper reported that "Deanna Cook was heard choking, gurgling and screaming 'Delvecchio, why are you doing this?'“ Patrick had several prior arrests for allegedly assaulting Cook and police had responded to the above address before.

Cook’s family wants to know if police could have done something to save her life. "We just deserve more answers than we're getting," said Cook’s sister, Gundy Karletha.

Police say the severity of the incident was not forwarded to them by the 911 operator. Sources told the newspaper that the 911 operator did not report that Cook was under attack just that there was a disturbance.

But the 911 operator, who was not identified, said she did not feel like she knew what was going on in the house. "I can say that it was obvious that there was an active disturbance taking place, yelling and stuff like that, I cannot say that I knew what exactly was happening, that there was an attack," the news media reported.

Gundy wants to know why the police did not make more of an effort to enter the house. "If they had kicked the door down, maybe they could have saved her," Gundy said. The day Cook was murdered, she tweeted that she was being threatened.

In a statement, the Dallas Police Department, said they were "trying to determine if the nature of the 911 call sufficiently communicated to the agents who responded the situation taking place.
