More than four decades after the ex-wife of Righteous Brothers singer Bill Medley was raped and killed, officials have named her suspected killer.
Karen Klaas was attacked on 30 January 1976 as she returned to her home in the Hermosa Beach area of California.
The 32-year-old was sexually assaulted and strangled with her tights, dying a few days later.
Although DNA testing was not used at that time, police had gathered and recorded items they hoped might be helpful in future, which turned out to be the key to solving the murder decades later.
