A 17-year-old has been charged with first-degree murder following a shooting at the Mall of Louisiana in Baton Rouge that killed one teenage girl and injured five other people, authorities announced Friday. The suspect turned himself in and faces five counts of attempted first-degree murder and one count of illegal use of a weapon, according to Lex 18 News.

The shooting occurred Thursday at the mall's food court when two groups of people met up, exchanged words and pulled guns, resulting in bystanders being caught in the crossfire, Baton Rouge Police Chief TJ Morse said. The incident was not random but appeared to be driven by social media disputes and possibly gang-related activity, Morse added. A second suspect remains at large.

Martha Odom, a 17-year-old high school student from Lafayette, was killed in the shooting. Odom was visiting the mall with friends for her senior skip day at Ascension Episcopal School. Two other students from her school were among the injured. The school described Odom on social media as "a joyful presence whose kindness and infectious enthusiasm brought light to all who knew her."

Louisiana Gov. Jeff Landry announced plans for a targeted warrant sweep focusing on neighborhoods connected to the suspects and vowed to crack down on gang violence in the capital city. "We are not going to allow our streets, our schools and our public spaces to become your battleground," Landry said at a news conference. He said he had spoken with FBI Director Kash Patel about coordinating state, local and federal resources to address the violence.

Two mall security officers ran toward the gunfire without hesitation and provided aid to victims, Morse said, crediting their quick action with saving lives. Five people were initially taken into custody but later released; the 17-year-old arrested Friday is the only person charged so far.

Under recently enacted Louisiana law, 17-year-olds are treated as adults in the state's criminal justice system. The deadly shooting marks the second high-profile case of gun violence in Louisiana this week, following a family shooting in Shreveport on Sunday that left eight children dead.
