As detectives worked to reconstruct the timeline, they began comparing the video with statements provided by individuals who had spoken with Nancy earlier that day. According to investigators, certain details did not align perfectly with the sequence of events seen on the camera recording. That discrepancy prompted detectives to take a closer look at other potential sources of evidence.
Attention soon turned to Annie Guthrie, who had reportedly been among the last people known to have interacted with Nancy before she went missing. Authorities emphasized that bringing Annie in for questioning does not necessarily indicate guilt, but rather reflects standard investigative procedure when officers need clarification about key details.
