The Last Take (21x22)

:

Christa Helm, an aspiring Hollywood actress, was murdered on Feb. 12, 1977, when she was stabbed and bludgeoned outside her agent's home in West Hollywood. Christa enjoyed the Hollywood life and parties, and according to her daughter hung out with lots of famous people, like Joe Namath, Mick Jagger, Warren Beatty and even the Shah of Iran. But as correspondent Maureen Maher reports, Christa also kept a "love diary," as well as tape recordings of her encounters with the rich and famous. Did the diary and recordings play a role in her murder? Or was she just a victim of a random crime? Investigators are still trying to solve the mystery.
