Death Valley National Park Service officials announced that Barker Ranch will be closed for up to four days later this month. A team of forensic researchers are following through on their February discovery of unmarked graves at the site where Charles Manson and his followers were arrested nearly four decades ago.

Digging was to have taken place in April but a piece of high-tech equipment was damaged in route to the site and the planned excavation was put off until officials were able to get another laser that will be utilized prior to any disturbance of the soil.

Manson and his group hid out at Barker Ranch after their 1969 L.A. killing spree, that included pregnant Hollywood actress Sharon Tate and her houseguests.
