26 years later and forensic testing solves a murder.

"AUSTIN (KXAN) - An anonymous letter sent to the Santa Ana Police Department in California led to an arrest 26 years after a young man was murdered. The suspect, the victim’s girlfriend, was arrested in Austin, Texas.
Santa Ana police say on January 4, 1996, they were dispatched to a call of a Black male suspect who had broken into an apartment and stabbed Christopher Hervey, 22, numerous times in his torso area. Hervey died at the scene.
Hervey’s girlfriend, Jade Benning, lived in the apartment and police said she made vague statements about the incident while they interviewed her in 1996. Neighbors reportedly told police they heard a loud argument in the apartment prior to the stabbing death.
Detectives say they were unable to determine exactly what happened to Hervey and the case went cold. Benning ended up moving to Austin."
