Penelope Jo Milbourn was 24 when she was last seen on June 7, 1988, in the Eureka, California area. At the time she was pregnant, struggling with drug addiction, and had an unspecified behavioral disorder. Her father reported her missing and the case is classified as endangered.

She is described as about 5 feet 6 inches tall, 130 pounds, with brown hair, blue eyes, and a tattoo of two roses on her upper right arm. She was known by the nickname Penny and was last seen in the Eureka and Fields Landing areas. Foul play is suspected but no significant leads have emerged and the case remains unsolved more than three decades later.

Does anyone who lived in Eureka or Fields Landing in 1988 remember Penny or have information about her movements that week?
