The Incident That Led to the Officer’s Charges
A Boston police officer has been charged with manslaughter following a fatal shooting that occurred during what officials described as an “unjustified” encounter. The incident involved Nicholas O’Malley, a 33-year-old resident of Randolph, who was charged after allegedly using lethal force against a man suspected of a violent carjacking.
During a tense arraignment at Roxbury District Court on Thursday, O’Malley pleaded not guilty. The courtroom was filled with dozens of his fellow officers, showing a strong display of departmental solidarity. However, the prosecution presented a detailed account of the events that led to the death of the suspect, Stephenson King, and argued that the use of lethal force was unwarranted.
The chain of events began on March 11, 2026, when a woman reported being assaulted and dragged onto the pavement while sitting in her running vehicle. The suspect, later identified as 39-year-old Stephenson King, fled the scene in her car. Later that night, O’Malley and his partner tracked the stolen vehicle to 10 Linwood Square.
According to the police report, the officers approached the car with guns drawn. King was found reclining in the driver’s seat. O’Malley moved to the driver’s side window while his partner took a position behind the vehicle. At this point, O’Malley allegedly drew a Taser and shouted at King, “Bro, I’m gonna f** shoot you!”
The situation escalated rapidly as King shifted the car into reverse, striking a police cruiser. He then moved the vehicle forward and backward again in a desperate attempt to maneuver away. It was during the final forward movement that O’Malley fired his gun at least three times.
King’s vehicle accelerated, crashed into a nearby stone wall, and came to a halt. Despite officers performing CPR at the scene, King was pronounced dead at the hospital at 10:24 p.m. An autopsy confirmed he had been struck three times. Notably, no weapon was found on King or anywhere inside the vehicle.
The Legal and Ethical Debate
The central conflict of the case revolves around whether O’Malley’s fear was “reasonable.” Immediately following the discharge of his weapon, O’Malley radioed that the suspect had “tried to run us over.”
However, Assistant District Attorney Ian Polumbaum told the court that body-worn camera footage tells a different story. Although the footage has not been released, the prosecution alleges that neither officer was in the car’s path when the shots were fired. Polumbaum stated that “O’Malley’s partner was more in danger from the shots fired than the driver’s vehicle.”
Under Massachusetts law, police are prohibited from firing into a moving vehicle unless it is strictly necessary to prevent imminent death or serious injury, and only if the force used is proportionate to the threat.
Reactions from the Police Union and City Leadership
The arrest has sparked a fierce backlash from the Boston Police Patrolmen’s Association. Union President Larry Calderone criticized the District Attorney’s office, accusing them of scapegoating an officer who had to make a split-second decision in a high-adrenaline environment.
“It’s very easy to come in Monday morning and take a look at a body camera and try to determine what an officer felt from your point of view,” Calderone said. “That body-worn camera doesn’t have human adrenaline. None of you know what it is to have your life, your partner’s life, or some other innocent victim, possibly their life in your hands, and have to make that determination in a split second.”
Calderone maintained that O’Malley acted out of a genuine belief that his partner was about to be crushed, regardless of what the later video analysis suggested.
Conversely, city leadership has supported the swift move toward prosecution. Mayor Michelle Wu praised the District Attorney and Commissioner for their urgency and commitment to transparency.
O’Malley, who has been suspended by the Massachusetts Peace Officer Standards and Training Commission, was released on his own recognizance on the condition that he surrender all firearms. The case is now expected to move to a grand jury, with O’Malley due back in court in May.
