CAMP FOSTER, Okinawa — A Marine warehouse clerk died over the weekend after his motorcycle hit a curb, sending him into a fence on a main thoroughfare in Nago city in northern Okinawa, according to the Marine Corps and local police.

Lance Cpl. Alexi Gamboa of 3rd Battalion, 12th Marines, 3rd Marine Division, was pronounced dead at 12:47 a.m. Saturday at Nago Hospital, the division said in a Monday news release.

Gamboa, from California, was based at Foster. He enlisted in the Marine Corps in April 2023 and was promoted to lance corporal in June 2024. His awards include the National Defense Service Medal and a Navy Achievement Medal, according to the release.

“Our thoughts and attention are directed with this young Marine’s family and friends,” battalion commander Lt. Col. Frank Mastromauro said in the release. “Lance Cpl. Gamboa will always be remembered with honor and for the impact he made across our battalion. His service and sacrifice will not be forgotten. The battalion stands united in grief alongside his loved ones.”

Gamboa was northbound on a section of Route 58 that curved gently to the right in the Kise district of Nago when his motorcycle hit the left curb and he fell off of it, hitting his chest, an Okinawa Prefectural Police spokesman said by phone Monday.

According to a Nago police spokesman, Gamboa “most probably” grazed the curb and flew off his motorcycle into a short, front-facing fence on a bridge.

“We don’t know why the accident occurred,” he said. “It’s not a dangerous place and there’s not much traffic.”

Flowers adorned the spot Monday morning where the collision occurred.

No one else was injured in the accident, 3rd Division spokesman 1st Lt. Joshua Figueredo wrote in an email Monday.

The accident is under investigation, the prefectural police spokesman said. The Marine Corps is working with police, according to the division release.

Four other service members have died in motorcycle accidents on Okinawa since 2024.

In May, Cpl. Nathaniel Curtis was killed and an unidentified Marine was injured in a three-vehicle accident in Nago’s Koki district.

U.S. Army Spc. DaJuan Cornish died in December after crashing his motorcycle into guard pipes on the left side of Road 130 heading toward Zukeran.

In November, Marine Lance Cpl. Avery Wayne Leverette was killed in a five-vehicle accident in the Yaka district of Kin town.

And in May 2024, Marine Sgt. Hayden Steingold died after colliding with another vehicle at a T-junction on Route 58 in Ginowan city.
