Serial killer on California's death row confessed to 1986 cold case homicide, authorities say

The discovery of an unsolved 1986 homicide case linked to a serial killer on death row was a significant breakthrough for Los Angeles County Sheriff's Department.

After 33 years of being a cold case, a chance discovery of evidence at another crime scene led detectives to revisit Small's case with new hope.

While initial investigative leads turned cold, a 2019 examination of materials unearthed connections that ultimately linked the unsolved case to a known serial killer.
