Edward Morales, the man accused of killing Mark Carson in a homophobic rage in New York City's Greenwich Village, on Tuesday entered a plea of not guilty.

According to court papers, prosecutors said that Morales told police after the shooting that he fired because Carson “thought he was tough in front of his bitch so I shot him. Diagnosis is dead, doctor,” the New York Daily News reported.

Police allege that Morales, 33, hurled anti-gay epithets at Carson, 32, and a companion as they walked down the street. He followed the men as they rounded a corner, then pulled out a .38 caliber revolver and killed Carson with one bullet to the head.

In other statements to police, Morales insisted that he couldn't remember the incident.

The slaying rocked the neighborhood known as the birthplace of the modern gay rights movement.

“This defendant is charged with targeting and gunning down Mark Carson on the streets of Greenwich Village because of his sexual orientation,” District Attorney Cyrus Vance Jr. said in announcing the charges against Morales. “Mr. Carson was murdered as he walked through a neighborhood that has long been a center of the gay rights movement and home to many LGBT New Yorkers, as well as a destination for LGBT visitors from around the globe.”

“Bias-related crimes have no place in New York City,” he added.
