In the quiet suburban landscape of Irvine, California, eighteen-year-old Janelle Cruz was embarking on a new chapter of her life. In May of 1986, while her family was away on vacation, she stayed behind, having recently started a new job at a local pizza restaurant. On the evening of May 4th, she was at her family's home on Encina with a male friend.
A series of unsettling noises outside, first thought to be a cat and then a sound from the garage, put them on edge, but a search of the property revealed nothing out of the ordinary. Her friend departed late in the evening, leaving Janelle alone in the house. The following day, a real estate agent arrived at the residence with the intention of showing the home to prospective buyers and made a gruesome discovery. Janelle had been brutally raped and bludgeoned to death in her bedroom. The cause of death was determined to be blunt force trauma to the head, and investigators suspected a pipe wrench that was missing from the home's backyard may have been the murder weapon. The crime scene was a chaotic tableau of violence, with bloodstains found in the kitchen and near the front door, suggesting a struggle before she was killed.
For years, the brutal murder of Janelle Cruz remained a cold case, a source of unending pain for her family and a frustrating puzzle for law enforcement. Investigators diligently collected evidence, including biological samples, but with the technology of the time, no suspect was identified. The case languished for over a decade until a breakthrough in 2001. Advances in DNA technology allowed investigators to link the evidence from the Cruz crime scene to a string of other murders and sexual assaults throughout California. This connected Janelle's murder to the notorious and elusive serial predator known as the "Original Night Stalker" and the "East Area Rapist," who would later be dubbed the "Golden State Killer." Despite this crucial connection, the identity of the killer remained a mystery for another seventeen years, leaving a trail of terror and unanswered questions across the state. The Golden State Killer was known for his meticulous planning and his ability to evade capture, leaving communities in fear and law enforcement with a seemingly unsolvable series of horrific crimes.
The long-awaited break in the case finally came in 2018 with the use of investigative genetic genealogy. Law enforcement uploaded the killer's DNA profile from the crime scenes to a public genealogy website, which led them to a distant relative of the suspect. From there, they meticulously built a family tree that ultimately pointed them to Joseph James DeAngelo, a 72-year-old former police officer living in Citrus Heights. On April 24, 2018, DeAngelo was arrested, bringing an end to one of the longest and most prolific crime sprees in U.S. history. On June 29, 2020, Joseph DeAngelo pleaded guilty to the murder of Janelle Cruz, along with twelve other murders and numerous other crimes. On August 21, 2020, he was sentenced to multiple life sentences in prison without the possibility of parole. The case of Janelle Cruz, the last known victim of the Golden State Killer, represents a chilling tale of innocence lost and a community terrorized. It is also a story of the relentless pursuit of justice by law enforcement and the revolutionary power of DNA technology that finally brought a notorious killer to account for his decades of horrific crimes, providing a measure of closure to the families of his many victims.
