Earl Gilmore (alias Earl Miller) is a convicted robber who previously served seven years for an armed robbery charge.
When Gilmore raped and shot Maggie Sandomir, her colleague and friend diagnosed with schizophrenia, Mark Nash, had a grief-stricken breakdown and attacked Gilmore in a rage, stabbing him in his upper body and genitals and leaving him barely alive in a trash can.
Nash, who refused psychiatric drugs and coped with his psychotic symptoms, was the prime suspect and forced on his meds. But Gilmore's real name was found out not long after he woke up and lied to the detectives, leading to his charges of rape and murder. Nash committed suicide when his lack of hallucinations drove him toward depression. (SVU: "Noncompliance")
