One of the people who had a child wounded in the shooting named Oasis Outback, which is accused of selling two assault rifles to the shooter.

The lawsuit also named Daniel Defense, the company that made the rifle used by the Uvalde shooter, as well as Firequest International, which makes accessorytrigger systems that the lawsuit said were "unreasonably dangerous and illegal."

Pete Arredondo, the school district police chief who was fired in August, and the city's then-acting police chief were sued by the parents.

Schneider Electric was sued by parents who claimed that the door at Robb Elementary School that failed to lock before the shooter used it to access the building was faulty and unsafe.

The parents are seeking a large amount of damages for a number of claims.

The slow response by law enforcement was found to be the result of "systemic failures" and "egregious poor decision making." More than 400 law enforcement officers responded to the shooting, but they waited more than an hour to confront the shooter. The police chief's testimony before the state senate was called an "abject failure" by the director of the Texas Department of Public Safety.

He told the Texas Tribune that he didn't feel like he was in charge of the response to the shooting. The principal has denied that the school was not adequately protected.

Tangent

Daniel Defense was criticized after the Uvalde shooting for its sometimes provocative advertising. A federal law shields gunmakers from lawsuits filed by victims of gun crimes.

The police chief of Uvalde School stepped down from the city council.

A state report found that the Uvalde school shooting response was Plagued by systemic failures.

The report says that Uvalde officers knew of injuries inside the school as they waited to confront the gunman.
