The California Department of Corrections has released the latest photo of serial killer Charles Manson, now 77, one week before his next parole hearing, CNN reports.

The photo, taken in June at the state prison in Corcoran, Calif., shows Manson with long, flowing gray hair, long beard and a mustache.

The photo was released at the request of CNN.

CNN notes that photos of prisoners are taken when they are transferred to other prisons or medical facilities or, in Manson's case, when an inmate's appearance changes.

Manson's parole hearing is set for April 11. The last hearing he attended was 15 years ago, CNN says, and he may not show up this time. He has been denied parole 11 times.

Manson was initially sentenced to death for the 1969 slayings of actress Sharon Tate and six others by a group of his followers.

The death sentence was changed to life in prison after California's death penalty was overturned for a period of time during the 1970s, CNN notes.
