Jose Gonzalez pleaded not guilty when he was indicted on first-degree murder charges in the death of Yadira Arroyo.
The mother of five was killed in March when police say Gonzalez got behind the wheel of her ambulance and fled, hitting the 14-year FDNY veteran.
The 25-year-old Gonzalez has a lengthy police record, including 31 prior arrests for criminal mischief, assault, marijuana sale and possession, turnstile jumping and public lewdness.
Most recently, he was arrested on Feb. 25 for allegedly resisting arrest and kicking out a window in a police van. Prior to that, he was arrested in June 2016 for assault and harassment, and reportedly released without bail in both cases.
