Melissa Sing is the widowed wife of Steven Sing, who died while attempting to arrest Jigsaw along with his partner David Tapp. She held Tapp responsible as it was his idea to investigate Jigsaw's lair without getting a warrant first. She began to neglect her and Steven's son Franklin. This led her and her son to be kidnapped by Jigsaw as part of Tapp's game in Saw: The Video Game. Melissa was put in a trap called the "Iron Maiden Trap", which would snap shut saw blades which would kill Melissa. Tapp managed to free her but she continued to blame him for her husband's death and told Tapp she could never forgive him. She had later ran off, leaving Tapp behind.
