On the morning of January 18, 1990, the body of 23-year-old Darla Jane Ferguson was found in a remote area east of Interstate 15 in Lake Elsinore, California. A jogger discovered her half-nude remains. Investigators determined she had been strangled so violently she nearly bit through her own tongue. Tire tracks at the scene were preserved and later matched to other crime scenes in the region.

Darla, known to law enforcement as a sex worker, was one of a series of killings in Riverside County in the late 1980s and early 1990s that shared a pattern of victims, killing method, and body disposal. Forensic links including tire impressions and pubic hairs connected multiple victims and drove the investigation toward a serial offender.

Did anyone in the Lake Elsinore area at that time have information about suspicious vehicles or people near Interstate 15 on January 18, 1990?
