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.

150 Stab Wounds

In 1969 an unidentified body (Jane Doe #59) with 150 stab wounds was found at Mulholland Drive. It was rumored that this was possibly the body of Sherry Ann Cooper.

The unidentified body remained a mystery for 46 years but in 2015 police have identified the woman as Reet Jurvetson, who moved to Los Angeles from Montreal the year she was killed.

Hi Daniel! I have heard conflicting stories
About “Simi Valley Sherry”….Obviously the one shown above, that Sherri lives in California under her marital name. I also
Read on a Family Blog that Sherry may have passed away from Cancer. Would love to know what really became of her, and see a recent photo if she is still among the living. I hope this helps!

Yes!!!! That would be sad if Sherry passed away!!! And I learned that, sadly, Juan Flynn has passed away as well!! Someone should find out for sure about these things!! I, myself, do not have the resources! But I know Juan has definitely passed!! And we don’t know if Sherry has, in fact, died!! Maybe she is still living!!

I know Sherry’s marital name and did some digging. I found her (last known) address and after some more digging I found her on Facebook and I can confirm she is alive and well. She looks good for her age.
