A television owned by mass murderer and cult leader Charles Manson is investigated by Zak Bagans on the latest episode of Ghost Adventures: Artifacts.

Manson, 82, is currently serving life in prison after being found guilty in 1971 of first-degree murder as well as conspiracy to commit murder over the deaths of seven people, including actress Sharon Tate.

A later owner has previously told how unexplained things began happening to after he brought the television into his bedroom — including his mother dying.

But when Manson’s grandson reveals he plans to get baptized, will that lift the curse that hangs over his family?

Ghost Adventures: Artifacts airs Saturdays at 9/8c on Travel Channel.
