Broadly, this act is known as "swatting" - a reprehensible way of seeking online revenge by getting a SWAT team sent to someone's house. The Los Angeles Police Department was investigating Barriss on allegations that he made similar calls in late 2017, and had planned a meeting with federal prosecutors before arresting the 25-year-old in connection with the Kansas incident. Here's a comprehensive write-up that details exactly how a tragedy like this could unfold.
For those unaware, "swatting" is when someone calls in a false police report that results in SWAT swarming in for an arrest, and Barriss has already faced prison time once before back in 2016. Barriss is being held on $500,000 bail. But causing a false alarm is not among the "inherently unsafe felonies" listed under the state's felony-murder statute, so prosecutors sought the manslaughter charge instead, Bennett said during a phone interview. According to the Kansas Statutes Annotated (Kansas' laws enacted by its state legislature), involuntary manslaughter is listed as a felony severity level 5. After this incident, an arrest was later made, and now the suspect has officially been charged with involuntary manslaughter for having his hand in the events that led to a person's death. "He doesn't play video games", Finch said.
One of the players allegedly called Barriss and requested he "swat" another player.
On the evening of December 22, officers were deployed to an apartment building in the community of Bankview after someone called 911 claiming that they had shot their father and taken members of their family hostage. Barris has a history of making such hoax calls, which are sometimes called "swatting". The woman involved in the Calgary incident reportedly told police that Barriss targeted her because of her online presence, according to Rolling Stone. Instead, one gamer is said to have provided two others with the Wichita address where Finch was killed.
Calgary tactical officers descended on the neighborhood, evacuating the surrounding area before a woman at the home also called police to warn them she believed she was the target of a fake call.
