Plastic Found on Deep In O’Keefe's Clothing Matches Karen Read’s Taillight - Forensic Bombshell
In this critical segment of the Karen Read trial, Massachusetts State Police Crime Lab forensic scientist Christina Hanley delivered testimony that bolsters the prosecution’s narrative: that John O’Keefe was struck and left to die—while key trace evidence ties back to Read’s SUV.
Hanley’s testimony focused on three main forensic categories: glass fragments, plastic from the taillight, and debris found in John O’Keefe’s clothing. Her analysis confirmed that six out of nine pieces of broken glass recovered from the road (Item 7-12) physically matched a drinking glass (Item 3-2) found shattered at the scene. These were “jigsaw-style” physical matches—clear, visible break lines that could not be coincidental.

Crucially, no glass from the bumper of Karen Read’s vehicle (Item 3-3) matched the cup. That undercuts any attempt to suggest the bumper glass proves an alternate chain of events. But the prosecution’s win didn’t end there.

Hanley’s testimony also tied red and clear plastic found on John O’Keefe’s shirt directly back to the passenger-side taillight of Karen Read’s SUV. The plastic wasn’t just “similar” in color—it was microscopically and instrumentally consistent, meaning it shared the same optical, structural, and chemical characteristics under forensic analysis (including FTIR and microspectrophotometry).

Although forensic scientists stop short of declaring a definitive source, “consistency” across multiple scientific instruments is the gold standard in trace evidence—and the jury heard that loud and clear.

This detailed forensic testimony is a massive problem for the defense. The physical match confirms O’Keefe was in proximity to the cup and the scene. The trace plastic suggests direct contact with Read’s vehicle. And no glass evidence ties back to any other suspect.
