In Lake Charles, Louisiana, four girls have been arrested for stabbing a fifteen-year-old girl in Walmart this Saturday.

The girls were 12, 13, and 14. Where the fifteen-year-old girl was stabbed is unidentified, but when she was at the hospital, she was pronounced dead.

According to Fox News, “Calcasieu Parish Sheriff Tony Mancuso said at a press briefing late Sunday that knives were stolen “from the actual store where they were… This is just a problem we’re having with kids having access to weapons. In some cases, stealing weapons,” Mancuso said. “It’s really heartbreaking when we have to come in and pick up the pieces because so many families are damaged after this.””

One of the girls were charged for second degree murder while the other three were charged with principal to second-degree murder.

ABC News reported, ““Our whole case unfolded before us through live Facebook and Instagram … we have videos of everything that took place and it’s very disturbing,” said Mancuso. “The whole murder was played out on [social media] so, again, there appeared to be no remorse. It was very cold to see 12, 13, 14 and 15-year-olds acting this way and we as a society can’t tolerate it. We cannot let this plague and take over our community.””
