Zak Bagans’ Haunted Museum hit its first anniversary earlier this month. The owner has another reason to celebrate after receiving a most prestigious donation. Bagans is said to have been gifted many items attached to the famed serial killer and cult leader, Charles Manson.

The items received include the hospital gown Manson was wearing at the time of his death, the coroner’s toe tag as well as all of the bone fragments. 

According to the Ghost Adventures star, Manson’s grandson, Jason Freeman, gave Bagans this collection this week. The new additions to the museum will be exposed as a predominant attraction at the Las Vegas location, which already features Manson’s false teeth and two paintings. One contains his urine and the other contains his ashes.

The bone fragments were scraped from the incinerator after Manson was cremated. Bagans is elated about his new artifacts.

“This is probably the most powerful possession I now own at my museum.”

One of the reasons why Freeman decided to give away these items was in part due to “possession.” Paranormal activity started occurring in his house, including an instance where he received a phone call from his home phone. No one was home at the time.
