As horrible as this is, at least he didn't use a gun.
Many more would have been injured/killed.
Five people were stabbed during a Hanukkah party at a rabbi's home in a New York suburb; a suspect has been arrested
Five people were stabbed Saturday night at an event at a rabbi's home in Monsey, New York, about 35 miles from New York City, said Ramapo Police Chief Brad Weidel. A suspect was arrested about two hours later in Manhattan as detectives sought to find a motive for the violence on the seventh night of Hanukkah.
The stabbings come after at least eight anti-Semitic attacks this month in New York City and following a Dec. 10 shooting at a kosher market in Jersey City, New Jersey, that left four dead. There have been a spate of attacks on Jewish people across the nation since late 2018.
