In October 1994, an unidentified woman was found buried in a shallow grave near Thousand Palms, California. The investigation suggested that the woman was a homicide victim. At the time of discovery, the Coroner's Office used all available resources to identify the victim, including having her DNA profile entered into the California Department of Justice Missing and Unidentified Persons System and into Namus as UP7040, but no identification was able to be made. With conventional STR testing not producing leads and other leads and tips exhausted, the case soon went cold.

In 2021, the Riverside District Attorney's Office contracted Othram to use advanced DNA testing to produce new leads in the case that might reveal the identity of the homicide victim or at least help find a close family member. Othram's laboratory team used Forensic-Grade Genome Sequencing® to generate a comprehensive DNA profile. This profile was delivered to investigators with the Riverside DA's Cold Case Team who used it to perform a genealogical search to find genetic relatives. Using the results of this search, the Riverside Cold Case Team was able to identify a candidate genetic relative -- one of her children. The Cold Case Team was able to find the biological child and a DNA sample was submitted to the California Missing and Unidentified Persons System. The parent-child relationship was confirmed, suggesting that in fact, the unidentified woman was Patricia Cavallaro, born March 22, 1937. She is suspected to be a homicide victim and an investigation into her death continues.
