Dan Erickson is a character in the Saw franchise.
Erickson was an FBI Agent who was later appointed to overlook the Jigsaw case. He relieved Peter Strahm of duty following his narrow escape from a Jigsaw trap and grew increasingly wary of him as Strahm became obsessed with Jigsaw. After he was informed by Mark Hoffman that Strahm believed there to be a second accomplice to Jigsaw, Erickson placed a trace on Strahm's mobile phone to locate him. Heading to the phones location, Erickson found a Jigsaw facility and a heavily injured Brit Stephinson and Mallick Scott, victims of a current game, before calling for paramedics.
It is later revealed Erickson helped Linsday Perez, having helped her fake her death for her own safety, to investigate Strahm's apparent link to Jigsaw. As they investigated, Erickson and Perez displayed suspicion of Hoffman, believing evidence implicating Strahm had been planted. Removing the distortion from the Jigsaw-styled tape found at Seth Baxter's trap, Hoffman was revealed as the true accomplice, forcing him to lash out and slice open Erickson's jugular vein. Erickson though was still alive as Hoffman poured gasoline on his body and set him on fire, finally killing him.
