Boston Officer with Clean Record Faces Manslaughter Charge After Taking Down Alleged Carjacker
A Boston police officer with six years of unblemished service is now facing a voluntary manslaughter charge after an on-duty shooting that followed a violent carjacking — and his attorney is sounding the alarm over what he calls a rushed and “unprecedented” move by the district attorney.
Officer Nicholas O’Malley, 33, was arrested March 19, just eight days after he shot and killed 39-year-old Stephenson King during a chaotic police response to a reported carjacking. According to police accounts, officers were dispatched after a woman called 911 to report that a man assaulted her, dragged her out of her idling vehicle, and sped away in it.
When officers confronted the suspect, the situation escalated rapidly. Authorities say King ignored lawful commands and created a dangerous scene, allegedly nearly backing over O’Malley’s partner before accelerating forward. O’Malley fired three shots during the encounter.
King reportedly had a lengthy criminal history that included prior gun charges and was well known to law enforcement.
Attorney: “Never Disciplined, Never Reprimanded”
O’Malley’s attorney, Ken Anderson, emphasized that his client has served honorably and without incident.
“He’s never been disciplined, never reprimanded — no trouble whatsoever,” Anderson said.
Despite that record, Suffolk County District Attorney Kevin Hayden’s office charged O’Malley with voluntary manslaughter, alleging the officer did not have a reasonable fear for his safety when he fired his weapon.
But Anderson argues the process was anything but ordinary.
- No grand jury had been impaneled.
- An internal firearm discharge investigation had not been completed.
- The arrest came just eight days after the shooting.
According to Anderson, officer-involved shooting investigations commonly take months before charging decisions are made. In this case, he says, prosecutors moved with unusual speed.
“They made a decision eight days in to arrest him without even presenting the matter to a grand jury,” Anderson said. “That’s disturbing.”
The attorney also questioned why his client — a lifelong Massachusetts resident, husband, father of two young children, and homeowner — was not simply allowed to turn himself in voluntarily. Prosecutors requested $25,000 bail, though O’Malley was ultimately released on his own recognizance and has pleaded not guilty.
Police Union Rallies Behind Officer
Support for O’Malley within law enforcement has been swift and strong. Numerous fellow officers packed the courtroom during his first hearing, standing in solidarity with a colleague they believe acted in defense of his partner and the public.
Larry Calderone, head of the Boston Police Patrolman’s Association, said critics who replay body camera footage from the comfort of an office chair cannot fully understand the split-second life-and-death decisions officers face.
“No one knows what it’s like to be a man or woman in uniform,” Calderone said. “It’s easy to second-guess after the fact. It’s different when you’re in the moment and lives are on the line.”
He described the entire situation as a tragedy but made it clear that the union stands firmly behind the officer, insisting the full facts will come to light.
Political Undercurrents Emerge
The case has quickly become a political lightning rod. District Attorney Hayden is up for reelection this year, and his handling of the case is drawing attention across the political spectrum.
Some local Democrats are reportedly considering primary challenges, while far-left Rep. Ayanna Pressley issued a statement expressing concern about the shooting and calling for transparency and accountability.
Critics of the prosecution, however, suggest the rapid charges send a troubling message to law enforcement officers who already operate in high-pressure, dangerous environments. They argue that charging a police officer before internal reviews are complete could have a chilling effect on proactive policing — particularly in violent crimes like carjackings.
At its core, the case raises serious questions about how America treats the men and women who put on the uniform each day to protect their communities. Officer O’Malley responded to a reported violent felony. A confrontation unfolded in seconds. A suspect with a criminal record is dead. And now a police officer with a spotless career record stands accused.
As this case moves forward, many will be watching closely to see whether due process is fully respected — not just for the suspect’s family, but for the officer who answered the call.
