Sherry Ann Cooper

Sherry Cooper, nicknamed Simi Valley Sherry, is a former member of the Manson Family. Sherry was the girlfriend of Manson Family member Danny Decarlo.

Sherry A. Cooper was born in 1953, in Los Angeles, California. She was known as a fun, loving, horse crazy girl. She drifted in and out of the Manson Family when the Family stayed at Spahn Ranch. Sherry lived at Royal Ave. in Simi Valley, approximately seven miles from the ranch.

Fun Fact

Ann is not her real middle name. Sherry gave the police a false name and date of birth when she was arrested. That false name and date of birth stuck with her and is frequently (mis)quoted/copy-pasted on other Manson related websites. Her real middle name starts with an A though, and her real birth year is 1953.

Spahn Ranch Raid

Sherry was arrested with the family during the Spahn Ranch raid. After the raid she moved to Barker Ranch in Death Valley with the rest of the Manson Family. 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.

Unidentified Body

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 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.

Decarlo was taken to Desert Hospital in Palm Springs CA. She had major head trauma. Decarlo was declared brain dead nine days later and taken off life support.

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.

Thank you RXSTR. Sherry was one of my best friends. She lived around the corner from me in Simi. We became fast friends even though she was a grade behind me. She invited me to go horseback riding at Spahn Ranch several times but my mom drove me there once, took one look around and refused to let me out if the car. We saw each other a few times after that. In 1971 one of our mutual friends told me that Sherry was in the mental hospital where she worked and her mind was gone because of all the drugs she had taken at the ranch. So for all this time I figured she was either mentally insane or dead. It’s good to know she is alive and not in a mental hospital. She was one of the sweetest, nicest friends I have ever had. My name is Janine Boe. My email is ***@gmail.com if you have a picture of her that I can see.
