Update: KWCH News has reported that 25-year-old Tyler Barriss of Los Angeles has been arrested in connection with the swatting. This isn't the first such incident in which Barriss has been involved: In October 2015 he was charged with making two fake bomb threats against ABC Studios in Glendale, California. According to Central Track, he may also have been involved in multiple bomb threats made against a Call of Duty: WWII tournament that took place earlier this month in Dallas, Texas. Barriss isn't identified by name, but the report indicates that the Swautistic Twitter account claimed responsibility for "ruining the whole event."
28-year-old Andrew Finch of Wichita, Kansas, was killed last night by police in what appears to have been an incident of "swatting." Deputy police chief Troy Livingston told the Wichita Eagle that police were responding to a report of a murder and hostage situation at Finch's home when he came to the front door and was shot.
The report turned out to be false, however. More than a dozen people "who identified themselves as being in the gaming community" told the Eagle that it arose out of a dispute between two Call of Duty players, Miruhcle and Baperizer, who were actually teammates in a losing match with a $1.50 wager riding on it.
It's not clear what sparked the trouble but at some point in the argument, according to this tweet (via Dexerto), Baperizer enlisted the aid of another player, who goes by the name Swautistic, to actually initiate the swatting. Miruhcle effectively dared him to do it, but provided a false address (but one that was apparently near his own), which led the police to the Finch home.
Swatting is a "prank" in which an aggrieved gamer calls in a false police report, accusing a rival of violent crimes serious enough to trigger a heavily-armed response. The police show up at the rival's door loaded for bear, everyone gets taken down, it takes hours to sort out, and in some cases it's all livestreamed.
It is also, quite obviously, a wickedly stupid and dangerous thing to do, making it even more appalling that this is something Swautistic known for (which is presumably why he was asking to do it): After reports of the shooting became public, CoD pro ZooMaa of Faze Clan claimed on Twitter that Swautistic has previously swatted, or threatened to swat, multiple other people.
Finch's family said in a separate report that he was unarmed when he went to the door, and that he didn't actually play videogames himself. Livingston said the police are looking into reports that the initial call to police was a false report; the officer who killed Finch for answering his front door has been placed on administrative paid leave.
Note: This article was edited on December 31 to clarify that Swautistic, and not ZooMaa, has previously swatted, or threatened to swat, multiple other people.
