This story was discussed on the forum earlier. Turns out that the boy who was killed had stayed in the house prior to the attack, with the homeowner's permission. So it was not a stranger-jumping-into-the-back-yard thing as originally reported.

08/11/19: Texas Teen Dies by Dog Mauling
Irving, TX - Early Saturday morning, three pit bulls secured in their fenced-in yard brutally attacked a 16-year old male. Irving police received reports of the attack about 4:45 am in the 800 block of East Third Street. Arriving officers jumped the fence and tried to stop the vicious attack by placing themselves between the teenager and the dogs, firing on the pit bulls in the process. One pit bull was shot in the jaw. The victim was transported to Parkland Memorial Hospital with critical injuries.
Nelson Cabrera, 16, succumbed to his injuries late Saturday. Cabrera did not reside at the home and police do not know why he was there.
The dogs also bit one of the officers, who was treated and released. "I commend those officers for taking the initiative to jump over that fence and think about the victim before themselves," Irving police public information officer Robert Reeves said. The owner of the pit bulls, Guillermo Lorenzo, shed no sympathy for the teenager. "He has no right to be in [my] yard," Lorenzo said. "Nobody has a right to be in [my] yard." Lorenzo claimed his dogs were "doing their job" by protecting him.
Lorenzo is also a backyard breeder of pit bulls. On the day of the attack, Fox 4 News captured images of four pit bull puppies on Lorenzo's property. The female pit bull that was shot in the jaw, "Bella" was humanely euthanized due to "the severity of its injuries," police said. Lorenzo's other two adult pit bulls, "Bruce" and "Little Bit" (a longtime game-bred dog name), are being held in quarantine at the Irving Animal Shelter. Irving Police are still investigating the deadly dog attack.
