On March 27, 2025, a Contra Costa County jury convicted 34-year-old Kenneth David McIsaac (born 12/20/90) on multiple felony charges, related to a home invasion incident involving a Lafayette family.
The conviction stems from a September 24, 2022, incident in Lafayette. As a mother and her children returned from the community pool in their apartment complex, McIsaac, who was also a resident at the same complex, followed them into their unit, shut the door and announced he was there to rob them. He lifted his shirt to reveal what appeared to be a firearm, later found to be a replica.
The mother called for her husband, who entered the living room. McIsaac forced the family to sit on the floor, retrieved kitchen knives, and handed the mother duct tape to bind her husband and children before binding her himself. For over five hours, he held the family captive and threatened to kill the parents in front of the children.
Through will and determination, the husband was able to free himself from his bindings. When McIsaac returned to the living room, the husband fought back, ultimately subduing the intruder long enough for the rest of the family to escape and seek help.
In August 2023, McIsaac was referred to Mental Health Court for diversion — despite objections from the District Attorney’s Office. He was accepted and released to a treatment facility — but fled in October.
Law enforcement apprehended him on November 14th.
McIsaac was convicted by a jury on multiple felony charges, including:
- Two counts of kidnap to commit robbery
- Two counts of kidnapping for ransom
- Multiple counts of first-degree residential robbery
- Felony child abuse
- False imprisonment
- Criminal threats
Additionally, the jury found true enhancements for the use of a deadly weapon in 12 of the 13 charges.
District Attorney Diana Becton stated: “This verdict holds Kenneth McIsaac accountable for the harm he caused this family. His conviction sends a strong message that violent crimes of this nature will not be tolerated in Contra Costa County.”
McIsaac is scheduled to be sentenced on June 6th by Judge Mary Ann O’Malley in Martinez. He faces a potential life sentence.
According to localcrimenews.com, the six-foot, three-inch tall, 190-pound McIsaac was also arrested in October 2020 by Oakland Police for battery with serious Bodily injury and elder or dependent adult abuse.
According to the Contra Costa Sheriff’s Department, he is being held in the Martinez Detention Facility on no bail.
