(CNN) -- Jon Opsahl said he doesn't think domestic terrorist-turned-housewife Sara Jane Olson served nearly enough time for his mother's murder, but he's relieved the saga ended with Olson's Tuesday release from prison.



Sara Jane Olson was released from a California prison Tuesday after serving seven years.



Olson, a member of the self-styled revolutionary Symbionese Liberation Army -- perhaps best known for kidnapping Patricia Hearst -- was released from a California prison after serving seven years, the California Department of Corrections and Rehabilitation said.



She was released to her husband just after midnight and is expected to serve her yearlong parole term in Minnesota -- over the the objections of police unions and Minnesota Gov. Tim Pawlenty.



Her sentence stems from her involvement in the 1975 attempted bombings of two police cars and the slaying of Myrna Opsahl during a bank robbery that same year.



Back then, Olson went by her birth name, Kathleen Anne Soliah. After her 1976 indictment in the attempted bombings, she changed her name and started a new life in St. Paul, Minnesota. She was not apprehended until 1999.



"I've really got nothing to say. She did her time, as minimal as that may have been," said Jon Opsahl, who was 15 when his mother was killed. "One of those years -- just one -- was for the murder of my mom and the bank robbery up in Carmichael."



Myrna Opsahl, a mother of four, was depositing money at the Crocker National Bank for her church when she was shot by Olson's co-defendant Emily Montague Harris, according to court documents. Harris was sentenced to eight years; she served four and was released on parole in February 2007.



Jon Opsahl, now 49, said he never understood why it took so long to bring his mother's killers to justice. While charges were filed in the bombings within months, no charges were brought in his mother's murder until 2002.



"You expect thugs to do what thugs do, but you don't expect the district attorney to turn a blind eye to the murder of an upstanding citizen," Jon Opsahl said Monday.



Olson's release Tuesday will cap an oft-strange storyline that spans more than three decades and which saw Olson wear the hats of college student, 1970s radical, housewife and philanthropist.



Attorney Andy Dawkins met Olson, now 62, shortly after she moved to St. Paul through friends in the reggae band, Pressure Drop. Fred Peterson, Olson's husband, played trumpet in the band, Dawkins said.



"She did good deeds everywhere. She raised three wonderful daughters. It was always a shock to all of us that the Sara we know had that past," Dawkins said.



After attending the University of California, Santa Barbara, Olson moved to Berkeley in the early 1970s. There, she met Angela Atwood in 1972, and the two became best friends and roommates, Olson told L.A. Weekly in a 2002 interview shortly before she was imprisoned.



After Atwood and five other SLA members were killed in a 1974 gunfight with the Los Angeles Police Department, Olson appeared at a memorial in Berkeley's Ho Chi Minh Park to eulogize her friend.



"SLA soldiers, although I know it's not necessary to say, keep fighting. I'm with you, and we are with you," Olson told the crowd.



Almost a year later, Olson took part in two bank robberies to help fund the SLA, according to court documents. During the Carmichael robbery, Olson "entered the bank with a firearm and kicked a nonresisting pregnant teller in the stomach. The teller miscarried after the robbery," the documents said.



In August 1975, Los Angeles police found homemade bombs under two squad cars. They were designed to explode when the car moved, but neither device detonated.



Authorities cast the attempted bombings as payback for the bloody shootout that left Atwood and other SLA members dead.



A probe into the gunbattle helped police arrest Hearst, the granddaughter of publishing mogul William Randolph Hearst, who claimed she had been kidnapped, raped and
