New Phil Spector Prison Mugshots Released

Two new photos of the former record producer and songwriter Phil Spector show the toll prison life has taken on him.

The most recent image, from October 2013, shows a bald, sombre-looking Spector staring straight into the camera.

The 73-year-old is serving 19 years to life after shooting the actress Lana Clarkson at his California mansion in 2003.

An earlier photo of a smiling Spector is dated July 24, 2013.

Before his conviction, Spector was known for the array of wigs he would wear in public and during his two trials in 2007 and 2008.

California Department of Corrections spokeswoman Terry Thornton said the October photo was taken when Spector was moved to the prison system's huge California Heath Care Facility in Stockton.

The facility provides medical and mental health care to the state's sickest inmates, including those with chronic conditions.

Ms Thornton said she could not reveal details of Spector's health because of state medical privacy regulations.

Spector always maintained his innocence and claimed Clarkson died from accidental suicide.

A 2013 HBO film called Phil Spector, written and directed by David Mamet and starring Al Pacino as Spector and Dame Helen Mirren as a defence lawyer, depicted a fictionalised account of the murder and trials.

Spector became known for his Wall of Sound production method. He worked with a number of huge stars in the 1960s, co-writing the Righteous Brothers hit You've Lost That Lovin' Feeling.

He produced The Beatles' album Let It Be in 1970.
