The murder of Debra Lynn Bonner further established the emerging pattern of targeting vulnerable young women. Like earlier victims, she was associated with prostitution and was last seen in areas frequented by Ridgway. The similarities between cases began to raise concerns among investigators.
Ridgway approached Bonner, gained her trust, and murdered her before disposing of her body in the river.
The discovery of multiple victims in the same river began to suggest a serial offender. Authorities started to consider connections between cases.
