Jimmy Dean Duncan was identified as the lead suspect in the 1975 home invasion rape and murder of 19-year-old Deborah Tomlinson in Grand Junction, Colorado. The case was cleared by exception due to the death of Duncan.
On December 27, 1975, an intruder had broken into Tomlinson’s home. She was bound, sexually assaulted, and strangled to death. Her body was found in her bathtub when the building manager telephoned police for a welfare check.
The FGG investigation was conducted by Parabon Nanolabs. Duncan, who was 26 years-old at the time of the murder, is reported to have passed away in 1987. The DNA match was confirmed with the assistance of an unspecified living relative, who cooperated with investigators.
