A white Chicago police officer who fatally shot a black 19-year-old Northern Illinois University student and accidently killed a neighbor has filed a lawsuit against the teenager's estate.
Robert Rialmo argues the shooting left him traumatized. His lawsuit filed Friday provides the officer's first public account of how he says the December 26th shooting happened. It says Rialmo opened fire after Quintonio LeGrier swung a bat at his head.
