On December 19, 1986, 28-year-old Jill Allen, a Caucasian woman working as a sex worker, was found beaten and strangled alongside Interstate 70 in Springfield, Illinois. Her underwear, bra, and shoes were missing. Those details matched the pattern attributed to a CB radio–using suspect known as Dr. No, who was linked to several mid-1980s murders of sex workers across multiple states, including Shirley Dean Taylor and April Barnett, both reported beaten, strangled, and found with clothing missing.

Despite the similarities to the Dr. No cases, no arrest was ever made in Jill Allen’s 1986 killing and the investigation went cold, leaving family and the community without closure. Is there anyone who remembers seeing suspicious activity along I-70 near Springfield in December 1986 or who has information that could help reopen this case?
