Antoinette Brown, 52, died after being mauled by six dogs loose in her South Dallas neighborhood last month

A helpless woman screamed for at least 20 minutes while a pack of dogs ripped her to shreds last month, 911 calls from her terrified neighbors have revealed.

Antoinette Brown, 52, was attacked by six dogs in south Dallas, Texas, on May 2, and died from her injuries a week later.

On Tuesday, police released two 911 calls they received from her worried neighbors, who were too scared to run out and save the woman.

The calls further confuse authorities' version of events, which says cops arrived on the scene just seven minutes after the first call. The audio proved that when the second caller phoned 20 minutes later, the woman was still being attacked.

The first call was placed by neighbor Jackie Humphrey at 4.43am, who told police: 'She’s out there begging for somebody to help her. I know some dogs was out there and somebody came and ran them off. But she’s still out there moaning and groaning and I’m scared to go outside.'

Ms Humphrey said she could hear Brown out in the street, yelling: 'Somebody help me. Help me! Somebody, help me!'

'I’m calling because there’s a woman out here somewhere - I looked out there but I’m kinda scared I can’t find her - but now she’s out there begging for somebody to help her,' Humphrey says.

'She’s been doing it - moaning and groaning - and if something happens to her I would feel bad if I didn’t call y’all to come out here and check it out,' Humphrey adds.

The dispatcher then reassures Ms Humphrey that help is on the way.

Another neighbor identified as 'Kenneth' frantically called the police 19 minutes after Ms Humphrey.

He said the woman was still out in the street being attacked by several dogs. That contradicts police reports which claimed they arrived on the scene at 4.50am.

'Is the female moving around?' the dispatcher asks.

'Yeah, miss, that’s what I’m saying is some dogs are attacking. We can’t get close to her,' he replies.

'Oh, they’re attacking her right now?'

'They attacked me too,' the man says. 'She’s in the field laying down, calling for help. I can’t do nothing.'

The dispatcher asks Kenneth if he can throw something at the dogs to get them off the woman, but he says he has already tried and that the dogs won't let him near her. Police arrive by the end of his phone call.

Meanwhile, Brown's daughter Matisha Ward spoke out to WFAA, saying she is grateful to the two neighbors who alerted police.

'My mama wouldn’t have even made it out of that field if that lady wouldn’t have called,' she said.

The family is considering filing a lawsuit against the city for $5million

The Army veteran and grandmother was found with more than 100 bites across her body in an empty lot, as the dogs had already fled from the scene, CBS Dallas reported.

Humphrey, told Fox 4 that she called 911 when she found Brown severely injured.

'One of her legs looked like a shark had taken a bite out of it,' Humphrey told Fox 4.

Humphrey said that she tried to have Dallas Animal Services capture the same dogs a year ago after she claims one killed her Chihuahua.

She explained to Fox 4 that when she called 911 about Brown's attack, police told her to call 311 about the dogs being loose.

Humphrey claims that she was told by an official that no one would come to the neighborhood for 72 hours.

'I said, 'Evidently, y'all are not communicating or something,' Humphrey told Fox 4.

Other neighbors claim that the aggressive dogs would roam the neighborhood frequently after getting out through holes in fences.

Now, city officials plan to revisit the policies on loose dogs after Brown's tragic death.

Dallas Mayor Mike Rawlings stated that Dallas Animal Services has 'to do a better job picking up stray dogs.'

'The priority has not been high enough, obviously,' Rawlings said. 'Progress is great, but we were in a deep hole and we have a long ways to go.'

He added that when someone is injured by an animal that the city's animal services needs to be contacted as soon as it happens.

According to Fox 4, the director of animal services created a plan to hire nine more employees eight months ago and five of the positions were empty for a year.

Humphrey believes that had Dallas Animal Services listened to the complaints from the neighborhood a year ago, Brown would still be alive.

'It seems like to me they don't care,' she told Fox 4. 'They really don't care.'

The case is still under investigation and no charges have been filed.

Authorities believe that they have identified the owner of the loose dogs who attacked Brown.
