Kristiana Coignard’s shooting death by police officers has one group ready to retaliate.

The online hacker group “Anonymous,” which famously retaliates after police shootings, including the Michael Brown shooting in Ferguson, Missouri, last year, has promised to seek vengeance on behalf of 17-year-old Kristiana Coignard, who was shot in a Longview, Texas police station lobby last Thursday, allegedly by police officers.

According to the Inquisitr, Kristiana Coignard was killed in mysterious circumstances after she reportedly walked into the Longview police station lobby, used a courtesy phone and asked to speak with an officer.

“When Officers arrived they were confronted by a white female who threatened them,” according to the Longview Police Facebook page. “The suspect brandished a weapon, made threatening movements toward the officers and was shot.”

Kristiana Coignard was reportedly shot “multiple times” by as many as three officers. She was pronounced dead at the hospital after being transported there following the shooting.

Police have yet to release existing video or audio of the incident and little is known about what happened, apart from the statement released by police.

On Saturday, a YouTube video was posted on an account allegedly affiliated with Anonymous threatening to seek some sort of revenge.

“We ask you Longview police department are you happy with the choice of how the actions taken be your officer? We ask you what kind of people you hire as a police officer that can’t take a knife from a small 17 year old girl?” the group wrote on the AnonSec 101 YouTube page. “We ask you why are your officer’s carrying tazors (sic) if they will only reach for their guns first? A firefighter will endanger their life and enter a burning building for the POSSIBILITY of saving a life, a lifeguard will risk drowning, for the possibility to save a life. A COP, will kill you OR a 10 year old child because you POSSIBLY could have caused them harm.”

In fact, the group claims they have already attacked the city’s website. However, there has been no confirmation by city officials that any cyber attack has occurred.

“Trust us when we say we wouldn’t have made this video if we knew the op wouldn’t be a success, we did make our statement, the site was down last night then the attack halted, then earlier today we started the attack again, it lasted awhile, then they finally decided to patch their security, lulz.”

The Texas Rangers are investigating the shooting incident of Kristiana Coignard.
