(CBS/AP) CORCORAN, Calif. - The parole hearing Wednesday at Corcoran State Prison in California is Charles Manson's 12th, and could be the last one for the aging mass murderer.

Manson, 77, has sent word that he doesn't plan to attend what might be his final chance to ask for freedom.

Under current law, inmates can be denied the chance to reapply for parole for up to 15 years. Another rejection could make Manson 92 before he would get another opportunity to make his case.

"At his age, I think he doesn't care," said Deputy District Attorney Patrick Sequeira, who will argue Wednesday against Manson's release. "He would be lost if he got out. He's completely institutionalized."

Manson could change his mind and attend the hearing if he has something to say but he has not appeared since 1997. His most recent hearing was in 2007.

Debra Tate, sister of murdered actress Sharon Tate, hopes Wednesday is the last time she has to argue in front of a parole board panel that Manson should not be freed. For four decades, Tate has traveled to whatever rural California prison Manson has been held in for hearings she says are too numerous to count.

"I've tried to take this thing that I do, that has become my lot in life, and make it have purpose," says the 59-year-old Tate, who was 17 in August 1969, when Manson sent his minions across LA on two nights of terror. "I've been doing it for Sharon and the other victims of him for the last 40 years."

Tate told The Associated Press she is hoping to look Manson in the eye while she reminds the two-member parole panel of the tortuous deaths suffered by Tate, who was 8 months pregnant, and four others visiting her Benedict Canyon home.

"I want to lock eyes with him and walk them through everything done to each and every one of my friends, blow by blow," she said.

Manson will be represented by state-appointed attorney DeJon Ramone Lewis, who told CNN he will urge the state to put Manson in a mental hospital.

Lewis said he is unsure of Manson's plan. If Manson does show, it would be the first time the two have met - Manson declined a meeting a month ago when Lewis went to Corcoran State Prison to prepare for the hearing.
