Patricia Skiple, known to friends and family as Patsy, was 45 when her body was found on June 3, 1993, on the side of California State Route 152 near Gilroy, California. At the time she was unidentified and was referred to as Blue Pacheco because of the color of her clothing. The cause of death was initially listed as undetermined.

Keith Hunter Jesperson later confessed to sexually assaulting and killing a woman near that stretch of highway; he was arrested in 1995 and ultimately confessed to multiple murders between 1990 and 1995. Jesperson pleaded guilty to Skiple’s murder in 2007 and received four consecutive life sentences without the possibility of parole.

Skiple’s identity remained unknown for years until detectives reopened the case and worked with the DNA Doe Project; advanced DNA analysis and genealogical research led to her identification in April 2022, and her family learned what had happened nearly three decades after her death.
