Under a 2018 law, such investigations are standard procedure when someone dies during an incident involving on-duty police.
According to a preliminary investigation, Kaizen Crossen, a 39-year-old Irvington resident, shot and killed an unarmed 20-year-old man with a rifle on Myrtle Avenue. That man's identity had not been released as of Thursday evening.
Officers responded within minutes of the 11:30 a.m. shooting, the first of whom exchanged gunfire with Crossen and was hit in the legs. That officer's wounds were non-life-threatening, authorities previously said.
More police officers opened fire, and two other officers were hit. Those wounds were also non-life-threatening, the attorney general's office said.
Crossen was also hit and was pronounced dead at University Hospital.
