Family of Slain Pregnant Woman Protest at Dallas Police Headquarters

Family and friends of D'Lisa Kelley, a pregnant woman found dead in an abandoned home in March, say the Dallas Police Department isn't doing enough to solve the young mother's murder case.

Without posters, signs or chants, Kelley's loved ones gathered in protest outside of Dallas police headquarters Tuesday morning to bring awareness to a foundation started after Kelley's death and to also ask the DPD why an arrest has not been made in the 24-year-old woman's slaying.

The family said Kelley was on the way to a friend's wake when they received an accidental phone call from her where they could hear her involved in some kind of an argument.

"She was screaming, telling the person to 'Stop, get off me,' then he was telling her to 'Be quiet. Stop screaming. Oh, you want to be hard headed.' It lasted for a minute and 11 seconds and then she got quiet," said Jasmine Stewart, D'Lisa's younger sister. "I'm torn apart. I'm heartbroken. I'll never see my big sister again."

That call was followed by a text message from D'Lisa's phone that said she would call them later, but the call never came. The family called 911 and told them what they'd heard, but 911 operators did not immediately dispatch officers in the case.

Kelley was never seen alive again. After her death the created the Kelley Alert Foundation and is pushing state legislators to create a statewide alert, called a Kelley Alert, during the 2015 session that would bridge the gap between Amber Alerts and Silver Alerts by requiring an immediate police response when known violence has occurred. Kelley's family believes police did not take the call seriously and that more could have been done to find Kelley more quickly.

A 911 administrator was put on leave for the handling of this case, but has since been put back on regular duty.

Tuesday, Kelley's friends and family are also demanding answers from the police about the current homicide investigation, why no arrests have been made and why the police haven't used the community to seek information, according to a statement from Dominique Alexander, executive director of the Kelley Alert Foundation.

"Basically we want answers,” said Lashaun Steward, D'Lisa's sister. “They haven't been communicating with us. When they do call its every couple of weeks telling us the same thing. They are waiting on DNA results or toxicology reports."

The family said they still don't know how Kelley died, when she died or if there are any named suspects in the case. The lack of information only increases their grief.

"We're taking it day by day. It's hard, especially trying to raise her 2-year-old son and seeing him every day; not having any answers for him, it's hard," said Steward.

NBC 5 reached out to the Dallas Police Department for comment on the allegations by Kelley's family. Police told NBC 5 the murder is still under investigation and they try to communicate all the information they can to the family.
