An 18-year-old white man suspected of fatally shooting 10 people in a Black neighborhood in Buffalo, New York, appears to be the latest in a line of ¡°copycat¡± gunmen carrying out deadlier mass shootings inspired by previous attackers, experts warned on Sunday.

Payton Gendron, who surrendered to police on Saturday after the attack, apparently publicized a racist manifesto on the internet and broadcast the attack in real time on social media platform Twitch, a live video service owned by Amazon.com. Authorities called the mass killing an act of ¡°racially motivated violent extremism.¡±

Experts say the trend of mostly young white men being inspired by previous racist gun massacres is on the rise, citing recent mass shootings, including the 2015 attack at a Black church in Charleston, South Carolina, a 2018 shooting at a synagogue in Pittsburgh, Pennsylvania and a 2019 attack at a Walmart in a Hispanic neighborhood of El Paso, Texas.
