Evelyn Joyce McDowell, 21, was last heard from on November 14, 1983, in a phone call traced to the Chatter Box Bar in Clear Lake. During that call she told a friend someone was trying to get her before the line went dead. Earlier that night she had been with friends in the Napa area and left their car after an argument.

Her friend reported her missing on December 12, 1983. A few days after her last contact, McDowell’s mother received her daughter’s address book in the mail with a note from a man named Dave claiming he had found it on a Lucerne beach; investigators located him and ruled him out. A search where the book was said to have been found turned up a woman’s sock tied at both ends and filled with sand and rocks.

Investigations by the Winters Police Department and the Lake County Sheriff’s Office continued into 1984, with follow-ups and possible sightings checked through 1988. The Lake County Sheriff’s Office named a person of interest, Tony Aguilar, who was questioned extensively; he died in 2002.

McDowell was described as a 21-year-old Caucasian woman, 5 feet 5 inches tall, about 115 pounds, with brown hair and brown eyes and a small blue heart tattoo on her shoulder. Does anyone have information about her movements in late 1983 or early 1984?
