(Newser) – "You killed my baby," a woman screamed as she ran toward Tevin Biles-Thomas in a makeshift courtroom in a Cleveland convention center complex Tuesday, moments after the 26-year-old was acquitted of a triple murder on New Year's Eve 2018. "You have to be f------ kidding me," the woman yelled, per NBC. "I'm going to kill you." Sheriff's deputies tackled the woman before she could reach Biles-Thomas, the older brother of gymnast Simone Biles. She was identified as the mother of 19-year-old DelVaunte Johnson, one of three people killed in the shooting at a party at an Airbnb property in Cleveland. Biles-Thomas was also accused of killing 21-year-old Toshaun Banks and 23-year-old DeVaughn Gibson. Prosecutors said the shooting happened after a group of uninvited men tried to crash the party.
