Relatives of 17 children killed and two kids injured in Texas’ deadliest school shooting are suing Texas Department of Public Safety officers who were among hundreds of law enforcement that waited 77 minutes to confront the gunman at Uvalde’s Robb Elementary, lawyers announced Wednesday.The legal action against 92 DPS officers comes days before the two-year anniversary of the shooting in which an 18-year-old used an AR-15 to kill 19 students and two teachers in two adjoining fourth-grade classrooms. Relatives of most of those students killed and two who were injured also announced Wednesday that they are suing Mandy Gutierrez, who was the principal at Robb at the time, and Pedro “Pete” Arredondo, who was the school district police chief, for their “inaction” that day. The families’ attorney also announced Wednesday that the city of Uvalde will pay them $2 million to avoid a lawsuit. Additionally, the city will provide enhanced training for current and future police officers, designate May 24 as an annual day of remembrance and work with victims’ families to design a permanent memorial at the city plaza, among other things.
