A 74-year-old man has been convicted in the 1972 killing of a San Francisco nurse.
The family of 22-year-old Diana Sylvester embraced today as a jury found John Puckett guilty of first-degree murder.
Police say Sylvester had just gotten off work at the UCSF Medical Center when Puckett followed her home, where he sexually assaulted, strangled and stabbed her to death.
The case went cold for decades until investigators got a hit from a DNA database.
Puckett, a retired handyman, has been convicted repeatedly of sexual assaults.
Prosecutors say Puckett faces seven years to life in prison, based on the law in place in 1972.
He wasn't tried for the sexual assault because the statute of limitations on that crime had expired.
