Matthew K.S. Swanson, 20
Swanson loved the outdoors and hiked, biked and camped frequently when home in California. He also was a music buff and had two electric guitars with him in Afghanistan. He'd recently purchased a motorcycle there and hoped to drive it across the United States upon his return. Swanson died about three weeks after he was thrown from a military vehicle in Logar Province, Afghanistan and critically injured.
