Susan Peck is a villainess from "Innocence Lost", case #19 of the crime solving game Criminal Case (release date February 28, 2013). She was the owner of the Stone Cold Motel, where CCN intern Gail Harding went before being found dead after being encased in cement.
When approached by the player and detective David Jones, Susan was shown to be abrasive and callous in regards to Gail's death, asking them to be quick while investigating Gail's hotel room and offering little information about her (claiming her memory was "a fickle thing" that tended to fade when cops were around). Later on, Susan's fingerprints were found on the bag of cocaine Gail had in her hotel room, leading to police officer Eduardo Ramirez revealing Susan as a convicted drug dealer.
When confronted by the detectives, Susan denied selling the cocaine to Gail, claiming she had given her some of her personal stash and that she was certain someone had pressured Gail into buying the drugs. While it was insinuated by David that Susan might've killed Gail to cover up the fact that she provided her with drugs, it was ultimately proven that Susan had no involvement in Gail's death. Later on, though, chief Samuel King had the detectives re-investigate Susan, as he had heard claims that she was selling ecstasy to teenagers.
When confronted by David, Susan continued to claim she wasn't dealing anymore, while accusing the police of trying to have her hotel shut down. Upon searching a room in the motel, however, a bag of ecstasy pills was found, with Susan's fingerprints on the bag proving that the claims against her were true. David and the player then confronted Susan with the evidence proving she was selling ecstasy, with the evil Susan blasting the teens she had sold the pills to for not taking the bag with them before being placed under arrest.
