Quadruple murder suspect accused of killing 1-year-old at Dallas home commits suicide during police chase

 Police found 21-year-old Byron Carrillo shot himself about 200 miles south of the crime scene

The man suspected of killing four people, including a 1-year-old boy, and wounding a 15-year-old girl in a shooting at a Dallas home shot himself during a chase with law enforcement, police said Monday.

Dallas police said 21-year-old Byron Carrillo fled the home after the shooting Sunday afternoon and then stole a vehicle. When law enforcement officers were pursuing Carrillo in the Austin area, about 195 miles south of Dallas, he drove the vehicle into a ditch and fled, police said.

When officers approached Carrillo, he shot himself in the head, police said. Police said that he died on the spot.

Officers responding to a home in the city's far southeast neighborhood on Sunday found that five people had been shot. Three adults died at the scene; A 1-year-old boy and a 15-year-old girl were taken to the hospital, where the 1-year-old died and the teen was treated and released. A 13-year-old girl was also inside the home at the time of the shooting but was not injured, police said.

The Dallas County Medical Examiner's Office identified those killed as Logan De La Cruz, 1; Vanessa de la Cruz, 20; Karina Lopez, 33; and Jose Lopez, 50.

Police said Carrillo had an ankle monitor due to a 2021 aggravated assault charge, but it was disconnected at some point before or immediately after the shooting.

Texas Rangers will investigate Carrillo's death, police said.
