The house was purchased sight-unseen by a New Jersey-based couple, Rob and Allison Conti, in June 2015. Featured on "Ghost Adventures" and "Ghost Hunters, the S.K. Pierce Victorian Mansion is considered to be New England's most haunted. Resident spiritualists Memie and Ken Watson have counted at least 13 spirits in the haunted Victorian mansion.
