Sherry Cooper

Sherry Cooper, nicknamed Simi Valley Sherry, is a former member of the Manson family. Sherry was the girlfriend, and later wife, of fellow Manson family member Danny DeCarlo.

Sherry Ann Cooper (Ann is not her real middle name) was born in 1953 in Los Angeles, California. Sherry was known as a fun, loving, horse crazy girl. She drifted in and out of the Manson family when the family lived on the Spahn Ranch. Sherry lived in Simi Valley, about 7 miles from the ranch.

Sherry was arrested with the rest of the Manson family during the Spahn Ranch raid on August 16, 1969. After her release, she moved with the rest of the family to the Barker Ranch in Death Valley. Sherry fled the ranch with Barbara Hoyt after Hoyt overheard Susan Atkins confess to the Tate to Ruth Ann Moorehouse.

When Manson found out that the two girls had fled, he went after them. He found the two at a local diner. He tried to convince the girls to stay with the family, and gave them $20 after the two girls told him they wanted to leave. It is said that Manson later sent some of his family members after the girls to kill them, but they were unable to locate the girls.

Unidentified Body

In 1969 an unidentified body, Jane Doe #59, with 150 stab wounds was found on 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.

In 1970, Sherry’s then-boyfriend, Danny DeCarlo, was called to testify in the Manson trial. After the trial, Sherry and Danny moved to Canada where the two married. Sherry and Decarlo had a daughter named Gina who died in a car accident in 1991. From a newspaper article:

Gina Decarlo was traveling as a passenger in a vehicle eastbound on I 10 when the vehicle rear ended a tractor trailer rig. The accident happened on April 29, 1991 at 7:00 am. 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.


Sherry and Danny eventually broke up and got divorced. In 1977, Sherry married a man seventeen years her senior, and they are still together to this day. Today Sherry lives in a small town in Northern California.
