Boston Officer Charged With Manslaughter in Carjacking Shooting as Defense Blasts DA’s Fast‑Track Arrest
Boston police officer Nicholas O’Malley, 33, has been arrested and charged with voluntary manslaughter for the March 11 on‑duty shooting of alleged carjacking suspect Stephenson King, 39, after police say King assaulted a woman and fled in her vehicle. O’Malley, a six‑year veteran described by his lawyer as having no prior discipline, allegedly fired three shots after confronting King during what police call a chaotic scene in which King nearly backed over O’Malley’s partner before accelerating away. Suffolk County District Attorney Kevin Hayden’s office argues O’Malley killed King without a reasonable fear for his own safety, but defense attorney Ken Anderson is publicly calling the DA’s move “bold” and “unprecedented” because the internal firearms‑discharge investigation is unfinished and no grand jury was convened before the March 19 arrest. Anderson says the DA sought a $25,000 bond and is “trying to send a message,” criticizing the decision to arrest O’Malley just eight days after the shooting rather than allow him to surrender voluntarily, while police‑union leaders and rank‑and‑file officers are rallying to his defense. The case will test how far local prosecutors are now willing to go in charging on‑duty shootings as crimes and is already sparking wider debate over whether Hayden is fairly enforcing the law or making a political example of a cop involved in a fast‑moving violent‑crime incident.
