SAN DIEGO (FOX 5 DC) — - The Marine Corps says a 24-year-old platoon commander from the nation's capital has died after being injured in a rollover accident involving a light armored vehicle during training at Camp Pendleton, north of San Diego.

Officials on Friday said 1st Lt. Hugh C. McDowell from Washington, D.C., died Thursday morning. Six other Marines were taken to a local hospital with injuries, but none of those injuries were serious.

McDowell - who went by Conor - was on the verge of proposing to his girlfriend, his family told FOX 5 in Washington, D.C.
