The Calcasieu Parish Sheriff’s Office has arrested four young girls, who allegedly stabbed a 15-year-old girl to death at a Walmart in Lake Charles, Louisiana, on Saturday, according to a Facebook post by the department. 

One of the four girls took a video of the deadly incident that went viral. All four girls are between the ages of 12 and 14. 

The Calcasieu Parish Sheriff’s Office said they were called to the Walmart around 7:30 p.m. on Saturday and helped transport the 15-year-old to a local hospital where she later died, according to the Facebook post.

While juveniles are generally not named, in an effort to find one of the girls they released her name on Facebook and a grainy photo of her. 

They eventually arrested the four girls and found that one was 14 years old, two were 13 years old and one was 12 years old. All are being held in the Juvenile Detention Center and police said the 13-year-old has been charged with second-degree murder while the other three have been charged with principal to second-degree murder.

Sheriff Tony Mancuso was despondent during a press conference on Sunday night, begging parents to take more of a role in knowing where their kids are at all hours. He said repeatedly that juvenile crime is on the rise and that there is little police can do.

"This is the third homicide in six months that we've had that involved juveniles that range from 11 to 16 years old. They come from all backgrounds, all races. This is just a problem that we're having with kids having access to weapons and in some cases stealing weapons," he said.

"In last night's case, they stole knives from the actual store where they were at. It's really heartbreaking when we have to come in and pick up the pieces because so many families are damaged after this. It's a cycle we have to stop. This is not something we can police our way out of. I just don't feel like this is a police matter. This is a parenting issue," he added. 

The case gained notoriety because the video of the incident went viral, although police are unsure of how the attack made its way onto social media. 

 

“Because the videos contain juveniles we are not going comment on how the videos got on social media or who or how many girls were in the videos,” Kayla Vincent, the sheriff's spokeswoman, told local news outlet WWL4. 

Mancuso called the posts disturbing, with one of the girls in the video laughing as she said she stabbed the 15-year-old in the heart.

Vincent later said police believe the argument started at a nearby movie theater before the stabbing took place at the Walmart. 

In an effort to try to stop the youth violence, Mancuso said officers would be enforcing a curfew for children under 17.

“We’re asking everybody to step up and get involved. All of us: parents, grandparents, store owners. We can’t let this happen, because it’s going to get worse and it’s going to get completely out of control. We as a society cannot tolerate this behavior. We cannot sit back and let this happen,” Mancuso added.

He suggested parents be more aware of what kids post and see on social media. 

“We’re a good community … the majority of people that live in Calcasieu Parish are good people. We have to do something about it," he said.

"We cannot sit back and let them destroy not only their lives and your lives but other people’s lives. We have to take a stance as a community, and we’re only as good as you want us to be. We can’t make excuses for why they’re doing this — that won’t fix the problem,” he added, according to The American Press.
