A man from Georgia, accused of murdering both his estranged wife and her young niece at the apartment they shared with relatives, reportedly threatened to “shoot every child” and “eliminate everyone” at the residence before the crime, according to his wife’s mother.

“While they attempted to serve him legal papers, they couldn’t locate him,” Nakita Bruce, the mother of Tomekia Pullins, one of the victims, shared with local ABC affiliate WSB this week.

Suspect William Almond, 43, is accused of killing Pullins, 29, and her nephew, Dior Scott, at her family apartment on Friday. Almond and Pullins allegedly had marital issues and often fought over their kids, per Bruce.

The defendant had “told us plenty of times” that if the child didn’t come back, “he would pop every kid in here,” the grieving mom told WSB. “He will kill everyone in this house.”

According to Bruce, Almond allegedly tried to “get in through the door, but he couldn’t.” She said security footage shows him moments later allegedly shooting through a window and striking Pullins with gunfire.

“When he was not allowed in, [witnesses] say he broke a window and fired multiple shots inside, hitting both victims,” DeKalb County police officials report in a press release. Almond ran from the scene but was later apprehended without incident, the release says.

“I want to thank the DeKalb County Police Department for its swift and diligent work in apprehending the suspect in this heartbreaking case,” said DeKalb County CEO Lorraine Cochran-Johnson. “Their thorough investigation was instrumental in identifying these familial relationships and ensuring that the suspect was brought into custody.”
