A 20-year-old Camp Pendleton-based Marine was arrested on suspicion of homicide Wednesday for his role in a deadly St. Patrick’s Day fight at a Dana Point pizza restaurant, Orange County sheriff’s officials said.
Lance Cpl. Jack Griffin Isaacson is suspected of fatally injuring 38-year-old Laguna Niguel resident Michael Terry during the March 17 fight, according to the Orange County Sheriff’s Department. Terry died around 10 a.m. the next morning at a hospital.
The two men got into a fight around 7 p.m. at Beach Harbor Pizza, a restaurant near the Dana Point Harbor, sheriff’s officials said. Deputies were sent to the restaurant, where they found Terry gravely injured; witnesses said the other man fled before deputies arrived.
It was unclear if the two men knew each other prior to their altercation, officials said.
Homicide investigators identified Isaacson as the suspect and took him into custody Wednesday.
Isaacson is a mortarman assigned to the Camp Pendleton-based 1st Marine Division, according to a Marine spokesperson.
“We are closely monitoring the case of Lance Corporal Jack Isaacson, a 1st Marine Division service member recently taken into custody by the Orange County Sheriff’s Department,” Marine Capt. Matthew Wolf said in an email. “The Division is committed to justice and is fully cooperating with the investigating agencies.”
Isaacson joined the Marines in January 2019, according to Wolf.
Jail records showed Isaacson remained in custody Thursday afternoon in lieu of $1 million bail and was scheduled to appear in court Friday.
