Hanah Le Page found that bag on the side of Highway 395 in Adelanto.
Inside, she discovered several uniforms - one with ribbons and medals and the name F.O. Sutton.
She posted the photos on the ABC7 Facebook page, and she dropped off the uniforms at the Marine Corps recruiting office in Victorville.
"It's something important to somebody, you know? It's their livelihood in that bag. So, hopefully we'll get some luck," Le Page said.
Anyone with information is urged to contact the Marine Corps recruiting office in Victorville at 14190 Bear Valley Rd. #E.
