A Brooklyn man pleaded guilty to stabbing a West Babylon woman to death on New Year’s Day.
Kisjonne Campbell, 25, pleaded guilty to second-degree murder for the stabbing death of 21-year-old
Michaelle Jaccis on January 1, 2022.
Sometime after 2:00 p.m. on January 1, 2022, Jaccis, her fraternal twin brother, and her 15-year-old
brother were at their residence in West Babylon when Campbell knocked on the door. Her 15-year-old
brother answered, and saw Campbell was wearing all black with a ski mask around his neck, a jacket and
gray sneakers. The teen, who had never seen Campbell before, said that, when he opened the door,
Campbell asked him if he had a phone number for a cab company. The victim’s brother then looked up
a number and gave it to Campbell, who then left.
Jaccis’ brother then informed her about what happened, which prompted her to go outside for a short
drive in the family vehicle.
Shortly after Jaccis returned home, she was violently attacked by Campbell in front of her house. Her
brothers rushed to the door when they heard her screaming. When the brothers opened the door, they
saw Campbell, who was wearing the same clothing as he was wearing earlier when he knocked on the
door, furiously stabbing their sister. The brothers ran inside and called 911, but, by the time they went
back outside, Campbell was gone. Police spotted Campbell, who matched the description given by the
brothers during the 911 call, jogging down a nearby block. Upon seeing a marked police unit, Campbell
attempted to jump over a fence to flee, but failed. Campbell was taken into custody within seven minutes
of the original 911 call. Thereafter, Jaccis’ brother identified Campbell as both the man that originally
asked for the cab company number and as his sister’s killer.
Later that same afternoon, a knife with a broken tip was recovered by members of the Suffolk County
Police Department in the bushes of the house next door to the crime scene. It was later learned at the
victim’s autopsy that the tip of a sharp metal object was recovered from her skull. The ski mask was also
recovered nearby and possessed DNA that matched Campbell.
Campbell was transported to police headquarters where he spoke to detectives for approximately two
hours. During that videotaped interview, he stated that he had a relationship with Jaccis and took a cab
from the shelter where he was staying at to her home in Long Island that day. He admitted to having a
physical altercation with Jaccis, conceding that he punched her in the face. Campbell described a long
knife that he was carrying that day, but told police that he blacked out after he struck Jaccis.
On May 8, 2023, Campbell pleaded guilty before Supreme Court Justice John B. Collins to second-
degree murder, a Class A felony. Campbell is due back in court on June 9 for sentencing. He is expected to face 20 years to life in prison.
“This was a horrific and senseless act of violence.” said Suffolk County District Attorney Ray Tierney.
“Thanks to the swift response from Suffolk County Police Officers working that day, the defendant was
quickly apprehended before anyone else could be hurt. This guilty plea spares Michaelle Jaccis’s family
from having to relive this tragedy in open court and ensures that the public will be protected from this
