Patricia Monique Soltysik (May 17, 1950 – May 17, 1974) was an American woman who was best known as a co-founder and activist in the Symbionese Liberation Army, a far-left militant group based in Berkeley and Oakland, California.

According to later testimony by Patty Hearst, who had been kidnapped by the SLA in 1974 and later joined them, Soltysik was responsible for killing Marcus Foster, the black Superintendent of Oakland Public Schools in November 1973.

Soltysik graduated from Dos Pueblos High School in 1968 in the top 10 percent of her class, where she was elected student body treasurer.

He sought refuge in Oakland with white friends from the Black Cultural Association (BCA), whom he had met earlier while incarcerated at Vacaville Prison.

She had not been part of the prisoner outreach program conducted at Vacaville by UC Berkeley volunteers, so they thought that law enforcement would not look there for DeFreeze.

Evidence suggests that DeFreeze acted as an agent provocateur for the LAPD, and had been encouraged to join or catalyze radical activists in the Berkeley area.

Most of the early SLA members were drawn from a group that encountered DeFreeze at Vacaville, where they first met as Berkeley volunteers to the Black Cultural Association.

On November 6, 1973, in Oakland, California, three SLA "soldiers" fatally shot Dr. Marcus Foster, Superintendent of Public Schools, and badly wounded his deputy Robert Blackburn.

Joe Remiro and Russ Little were arrested in January 1974 after an armed confrontation with police in Concord, California, near where other members were staying at a house rented under a false name by Nancy Ling Perry.
