Convicted mass murderer Charles Manson is up for parole today after being denied parole 11 times since 1978. Manson was convicted of seven counts of first degree murder, and is currently in Corcoran State Prison serving a life sentence.

Manson boycotted his 2012 hearing today, in the past being quoted as saying he is a political prisoner. He has not shown up for several of his latest hearings, since 1997, California Department of Corrections spokesman Luis Patino told ABC News. He told his counselor that he did not plan on attending.

Manson's attorney, DeJon R. Lewis will be representing him at the hearing. Lewis is attempting to have Manson transferred to Atascado State Hospital. Charles Manson does not need incarceration at this point in his life, Lewis told CNN. He needs hospitalization.

The parole hearing could be anywhere from 30 minutes to several hours. Presentations from both sides will be made, as well as a review of psychological reports, prison records and documents form interested parties, reports ABC News.

Manson's last parole hearing was in 2007. He had been denied parole by the Board of Parole Hearings who believed that Manson, then 72-years-old, continues to pose an unreasonable danger to others and may still bring harm to anyone he would come in contact with.

In 2009 CNN reported that the killer had a laundry list of violations in prison that could crush his chances for freedom at the parole hearing. Some of these violations include being caught in possession of a weapon, threatening a peace officer and being caught with a contraband cell phone twice, reported ABC News.

Manson landed in jail after going on a crime spree in Los Angeles in August 1969. Manson's family went to the rental home of actress Sharon Tate on August 9. Eight months pregnant at the time, Manson's family murdered Tate and four others that were in the home. The next day the Manson family killed two more people.

Sharon Tate's sister, Debra Tate, is attending the hearing. Debra Tate has attended all of Manson's hearings over the past 15 years even though Manson has not attended himself. He needs to look into our eyes, victims' eyes, and see the pain that he has caused, Tate told CNN. I think that that is something that is essential to his coming to peace, perhaps before he passes.

If denied parole at this hearing Manson may not be eligible again until late 2027.
