Murphy was an ODST, present for the Battle of Reach and the following Battle of Installation 04. He was the driver of First Lieutenant Melissa McKay's Warthog on the way back to Alpha Base after the successful supply raid on the crashed UNSC Pillar of Autumn. During intense fighting, he embarrassingly urinated himself, but managed to drive the Warthog to safety. He was either killed during the battle, during the destruction of Halo, or when the captured Truth and Reconciliation was destroyed.
