On Friday, Chicago Police Officer Robert Rialmo filed a $10 million lawsuit against the estate of Quintonio LeGrier, a 19-year-old black college student he shot dead on Dec. 26, 2015, along with innocent bystander Bettie Jones, 55. In his suit, a counterclaim against a wrongful-death suit filed by LeGrier's estate, Rialmo claims that LeGrier charged at him with a baseball bat.
