A possible mass shooting at Tuesday’s Stanley Cup finale may have been thwarted by Las Vegas police, who arrested 33-year-old Matthew DeSavio after he made online threats to commit a massacre. “I’m coming for you guys tonight and I hope you get every [expletive] police officer in Vegas Golden Knights there to defend you!” said one message, according to local station KLAS. “Hope Sin City is ready for the Mandalay Bay massacre part duex [sic],” the New York Daily News reports His comment alluded to an October 2017 shooting where a gunman on the 32nd floor of the Mandalay Bay hotel in Las Vegas killed 61 people and injured hundreds more when he opened fire on the Route 91 Harvest music festival taking place below. It remains the largest mass shooting in U.S. history. Around noon this Tuesday, Las Vegas Metro police were dispatched to a business where DeSavio was making the threats and apprehended him. Someone at that business is said to have had a long history of being harassed by the suspect.
Cops had also been contacted by someone concerned with postings DeSavio made to Facebook about “conducting a mass shooting at T-Mobile Arena” where the Vegas Golden Knights won their first NHL championship Tuesday night. The suspect reportedly asked police if they’d seen his Facebook postings when he was taken into custody. One of those messages referred to the 2017 Las Vegas slaughter as “just a preview.” The suspect made a similar Facebook threat in October about duplicating the music festival massacre. A Nevada court ordered DeSavio to undergo a psychological evaluation in November, but the case against him was dismissed because the state was unable to provide that service in a timely fashion. DeSavio now faces charges including making a false threat regarding an act of terrorism and aggravated stalking.
