34 year old murder case solved via DNA.

"For more than three decades, the killing of 79-year-old Lucille Hultgren in her home in Galt has gone unsolved. It’s been the small Sacramento County community’s sole cold case murder.
But now a DNA match on the victim’s fingernail scrapings has identified Hultgren’s killer, a transient and sex offender who lived under a bridge on Highway 99 until his death in 2011, authorities said on Tuesday.
Hultgren was found dead at her home on May 23, 1988, by two friends who had come to check on her after she missed church, Galt Police Chief Brian Kalinowski said. She had been strangled, stabbed and sexually assaulted, he said
Authorities identified Hultgren’s killer as Terry Leroy Bramble. He was a longtime resident of Galt who was never on the radar of police until his death from natural causes. But his DNA was on file from a sex assault case in San Joaquin County that authorities are hoping to learn more information about.
Advances in analyzing DNA evidence over the years have reached the point where what used to require a sample the size of a quarter can now be “less than a billionth of the size of a Sweet'N Low package,” Schubert said."
