On July 23, 1998, Bravo team was sent into the Arklay Mountains to investigate the disappearances and brutal murders of hikers. Their helicopter experienced engine failure and crashed into the forest. The R.P.D. pilot, Kevin Dooley stayed behind to find the cause of the failure.
While Rebecca Chambers and Edward Dewey searched the Raccoon forest, the rest of Bravo Team - Forest included - found an abandoned Spencer Mansion. The team split up to check the area and report back with their findings. Unbeknownst to them, Kevin  and Edward were already dead, and Rebecca was unable to reach them for another day.
Whilst checking the second floor East terrace, Forest was attacked and pecked to death by a murder of crows.[excerpt 2] He then reanimated as a zombie and attacked his fellow S.T.A.R.S. members before finally being put to rest.[notes 1]
