A man was taken into custody in Mexico Sunday after he allegedly broke into his estranged girlfriend’s Lake Highlands home and fatally stabbed her, according to relatives and police.

Dallas police said officers found 35-year-old Daisy Moctezuma after she was stabbed Sunday inside a home in the 8300 block of Skillman Street at 6:38 a.m. Police said Jesus Leal Huerta has been arrested in Mexico in connection with Moctezuma’s death and attacking two minors while at the home.

The two minors were Moctezuma’s 16-year-old daughter and her 13-year-old niece, said Moctezuma’s sister Leslie Hernandez, 40. The two girls were able to get away during the attack and call Hernandez, she said.

Hernandez said her sister had been involved in a violent two-year relationship with her boyfriend that included physical and mental abuse.

“She was one of them girls…” she said. “She tried to get out and she couldn’t.”

Hernandez said her daughter and 16-year-old niece were having a sleepover to celebrate the beginning of school when Huerta broke into the home. The man allegedly choked Moctezuma’s daughter and went after her niece. Hernandez said she believes the man went after Moctezuma’s daughter as a way to hurt her sister emotionally. Moctezuma stepped in to protect the girls from Huerta, Hernandez said.

“She got in between them and told them to run, run, look for help, call 911, and she stayed in the apartment fighting with him.”

The girls found out after leaving the home that Moctezuma had been killed.

“They’re destroyed,” Hernandez said. “They’re scared.”

Hernandez said anyone who met Moctezuma saw she was beautiful inside and out. Moctezuma loved her family and taking care of others. She spent the last four years working at a retirement home in Dallas, her sister said.

“She was a great sister,” Hernandez said. “She was a good person. Everywhere she would go, she would dance, she would hear a little bit of music and she’d be dancing.”

Her sister said she was worried about her relationship with Huerta. She described him as possessive, as he would ask for her location multiple times and her sister would sometimes show up with bruises, Hernandez said. Moctezuma attempted to get a restraining order against Huerta but was unable to, Hernandez said.

“She tried to get help so many times and called the cops so many times,” her sister said. Dallas police did not immediately confirm if domestic violence was suspected and if domestic calls had been previously made at the Skillman Street address.

Huerta was taken into custody in Mexico later Sunday evening, police said. He is awaiting extradition back to Dallas County, where he will face charges of murder and injury to a child, according to authorities. Additional charges may also be filed as the investigation continues, police said.
