For other uses of this name, see Riley (disambiguation)
Senior Airman on board Destiny, and an expert in technological matters. Riley was a small-town boy far away from home: he grew up on a farm, and has relatives who have never left their home state. Originally assigned to Icarus Base, Riley's job related to Stargate operations at the facility, including dialing the gate. He was capable of reading the Ancient language and operated systems related to the Stargate aboard Destiny.
He was severely wounded several weeks after the reluctant crew's arrival on the ship, and was recuperating for several weeks. Shortly after his recovery he survived the Lucian Alliance incursion of the ship (suffering a head wound and being temporarily stranded on a barren alien planet). But it was a shuttle crash that finally did him in. Pinned under a collapsed bulkhead after the shuttle crash-landed on a planet, Riley knew that we would not survive. To end his intense pain and help his friends get back to Destiny in time, he asked Colonel Everett Young to end his life.
Riley died on the shuttle floor, smothered by his commanding officer.
Despite his team's dire predicament aboard Destiny, Riley insisted that he had no regrets. It wasn't so much being on the ship that bothered him, but not being home with his loved ones.
