DNA Technology Solves 2014 Park Stabbing, Leads to Murder Arrest After 12 Years

Twelve years after Labh Nigah was stabbed to death in an Oxnard park while elementary-school children watched from across a chain-link fence, forensic scientists traced crime-scene DNA through a genetic genealogy database to a relative in Houston, then to a sibling in Ventura County, and finally to Jose Antonio Jimenez, now 32, who authorities say was living just blocks from the park when the killing occurred.

Jimenez was arrested at his home on Thursday and charged with murder. Ventura County prosecutors added three criminal enhancements: use of a knife as a deadly weapon, inflicting harm in a manner described as "particularly cruel, vicious and callous," and ambushing a defenseless victim. Bail was set at $500,000, and he appeared in a Ventura County courtroom Monday for arraignment.

The killing occurred the morning of November 13, 2014. Nigah, a 55-year-old father of three, had stopped at Sierra Linda Park in Oxnard after walking his son to the adjacent elementary school. Witnesses, including school staff and students in the yard, observed the attack at approximately 8:43 a.m. Forensic sketches were circulated and investigators preserved biological evidence from the scene, but the case went cold for nearly 12 years.

The breakthrough came through forensic genetic genealogy, a technique that compares DNA from an unknown crime-scene sample against consumer genealogy databases to identify biological relatives of the contributor. Ventura County District Attorney Erik Nasarenko described the investigative chain at Monday's press conference: "Detectives were led to a relative of the defendant in Houston, Texas and later a sibling residing right here in Ventura County. Through that process investigators identified Jose Jimenez, who lived just blocks from the crime scene when the alleged murder occurred." Prosecutors credited the careful preservation of biological evidence collected in 2014 as essential to enabling that later analysis.

Oxnard Police Chief Jason Benites called the original crime "a truly heinous crime" and noted that it "occurred in broad daylight in a public park next to an elementary school that was in session." Prosecutors say there is no evidence Nigah and Jimenez knew each other before the attack. Nigah's daughter Arshneel Kaur, speaking with reporters after Monday's announcement, captured the family's fractured sense of relief: "I am still in a state of shock."

The case arrives at a contested moment for forensic genetic genealogy. Since the technique helped identify the Golden State Killer suspect in 2018, investigators nationwide have turned to consumer databases such as GEDmatch and FamilyTreeDNA to break cold cases. Both platforms allow users to opt in or out of law enforcement searches, but privacy advocates have raised alarms about investigations that reached profiles uploaded by people who explicitly declined to participate. The Justice Department's interim policy limits the technique to unsolved homicides and sex crimes, and Maryland and Montana have gone further, passing laws requiring court authorization before investigators access genealogical databases. The unresolved tension at the center of every such case remains the same: the relatives whose DNA profiles made the identification possible never consented to becoming investigative leads.

The Ventura County District Attorney's office said the investigation remains ongoing and urged anyone with additional information to contact authorities.
