A Bronx man pleaded not guilty in court Thursday to killing his ex-girlfriend, who was the mother of their child.

Police say Darrin Rose, 22, slit the throat of Zoila Feliz on Halloween night in her Soundview apartment. Their child was found unharmed near the body.

An order of protection for the toddler was extended Thursday.

Rose is charged with murder, manslaughter, assault and criminal possession of a weapon. He's due back in court Feb. 28.
