Sherry Ann Cooper

Sherry Ann Cooper, nicknamed Simi Valley Sherri, was born in 1953 in Simi Valley, California. Sherry Ann Cooper was the girlfriend of Family member Danny Decarlo.

Sherry was a local girl from Simi Valley. She drifted in and out of the Family when the Family stayed at Spahn Ranch. Sherry was arrested with the family during the Spahn Ranch raid.

She moved with the Family to Barker Ranch in Death Valley. Sherry Fled Barker Ranch with Barbara Hoyt after Hoyt overheard Susan Atkins talking about the Tate murder to Ruth Ann Moorehouse.

When Manson found out the two girls had run away he took off after them. He found them having breakfast in a diner and gave them $20 after the girls told Manson they wanted to leave. Story has it that Manson later sent three Family members to retrieve or kill the girls.
