Nothing is known about Joseph's life, except that he was known to be extremely curious, to enjoy danger, to be humorous and optimistic. Regarding his career, Joseph initially was a member of S.T.A.R.S. Bravo team, however, he would be promoted by Albert Wesker to the Alpha Team shortly before his teammates' investigation mission in the Arklay Mountains about the bizarre murders that took place in the region, which made his former team members a little jealous of his promotion.
After Bravo team lost contact with R.P.D., Joseph was among the Alpha team members when they discovered the wreckage of Bravo team's helicopter on July 24, 1998. Due to his curiosity in wanting to search the surrounding area for clues about the whereabouts of any of his colleagues, he was the one who finding the partially eaten corpse of Bravo team's pilot, Kevin Dooley.
Whilst searching through the forest, he was distracted by a pack of Cerberuses roaming the Arklay Mountains. Moving away from the rest of Alpha team, he was attacked by a number of Cerberus dogs en masse. Unable to fend off the Cerberus pack, Joseph was overwhelmed and his screams of pain alerted the other members of the unit. Fellow Alpha team member, Jill Valentine, attempted to help, unloading an entire pistol magazine into the pack, with no success. After killing Joseph, they quickly turned to Jill and the other Alpha team members, pursuing them towards the nearby mansion.
