Edward Mars known to the survivors simply as The Marshal, was a middle-aged U.S. Marshal who was travelling with his prisoner Kate back to the United States from Australia. He was one of the Flight 815 crash survivors on the mysterious island, but suffered severe injuries in the crash, and Jack finally put him out of his misery. He is played by Fredric Lehne and appeared in ten episodes.
Mars caught up with Kate as she was about to board a bus or train to Tallahassee. She fought back, but he caught her.
Mars was in Australia, either looking for Kate or acting on a tip from Australia. He caught her when she saved a farmer from a car accident she caused.
Mars was struck in the head by a heavy case when the heavy turbulence started mere moments before the plane broke apart. He was unconscious when the oxygen masks dropped, but Kate put one on him.
The Marshal remained unconcious for the first day and night, only waking up after Jack removed a piece of shrapnel sticking into his abdomen. His first concern was knowing where Kate was.
He knew he wasn't going to survive, so he asked Kate to end his life. She couldn't, but she gave Mars's own gun to Sawyer. Sawyer shot Mars in the chest, but missed his heart. Jack ended up being forced to smother him to end his misery.
Jack buried him away from the fuselage.
When Kate told him that the key needed to open the Marshal's case was in his wallet, Jack and Kate dug up the body to get the key.
