You want to talk about the cell phone data and the TechStream data? Great. Let's talk about it.
These are the facts presented at trial, and notably, the defense did not call an expert to refute them.
Karen Read was intoxicated. Her SUV recorded a reverse event reaching 74.5% throttle and speeds up to 24 mph. At the same time, Officer John O'Keefe's cell phone stopped moving. She then left him and phoned him within minutes to tell him she “f*cking hated him”.
The SUV stops at 12:24:38. There is no recorded movement for seven minutes. At 12:31:56, a brief 20-second step event begins. During that period, the phone briefly pings the house while refining GPS accuracy, but the latitude and longitude do not change.
At 12:32:09, the last user interaction with the phone occurs.
At 12:32:16, movement stops.
Beginning at 12:33:14, 26,532 Doppler checks consistently register a pocket state for more than five hours, indicating the phone remained stationary.
At approximately 12:37 a.m., the battery temperature begins dropping and continues to decline, consistent with the phone being outside in cold conditions.
Coincidentally, Burgess concluded that the second trigger event, 74.5% throttle and speeds up to 24 mph in reverse, occurred between 12:32:04 and 12:32:12.
Movement does not resume until 6:04:01 a.m., when Karen Read, Kerry Roberts, and Jen McCabe are performing CPR. The phone registers movement because it is underneath John.
Notably, after John is moved onto the stretcher and the phone is exposed, the device records its lowest temperature, 37°F, at 6:14 a.m.
At 6:15:01 a.m., Kerry Roberts is seen on dash cam picking up the phone and baby blankets. At that same time, the pocket state clears. Once the phone is placed in her pocket, the battery temperature begins to rise. It continues rising when she gets into a warm vehicle.
This conclusion was not based on one isolated data point. Ian Whiffin relied on multiple independent data streams: steps, Doppler pocket state, user interactions, battery temperature, and location data. All of them told the same story.
He concluded that John O'Keefe's phone never moved far from the flagpole area from 12:25 a.m. until it was recovered in the morning.
Before Trial 2, a full extraction was performed in the presence of both parties' experts.
Burgess used Karen Read's own timeline, vehicle mileage, surveillance video, John O'Keefe's phone data, steering wheel inputs during the trigger events, and the admitted three-point turn on the way to 34 Fairview. That analysis allowed him to identify Trigger Event 1 (the three-point turn) and align Trigger Event 2 with the reverse maneuver that occurred eight minutes and 5 seconds later in front of 34 Fairview at the same time John's phone recorded its last movements.
At 8:23 a.m., a police dash cam captured the damaged taillight in the driveway of 1 Meadows. Barros confirmed on cross and recross that the taillight damage visible in the wellness check image was consistent with what he observed in Deighton. He also testified that the image in the Sally Port was not consistent with what he saw at Deighton, and that's correct. The image of the SUV in the Sally Port was no longer covered and packed with snow as it had been when he first observed it in Deighton.
All of those independent data sources tell the same story: John O'Keefe never entered the home. His phone stopped moving at the same time Karen Read's SUV recorded a high-speed reverse event, and the cell phone remained stationary until John O'Keefe was found. Her taillight was damaged and missing the red lens before the vehicle was ever brought to the Sally Port.
If John never entered the home, then arguments about who called whom, who butt-dialed whom, whose wording changed across multiple sworn testimonies, and who remembers what become secondary questions.
As David Yannetti stated on your show, "testimony changing is not unusual ... it doesn't always mean someone is lying ... when you tell a story of what happened, you never tell it the same way twice." The more important question is whether the objective digital evidence changes.
It doesn't.
That's why the phone data, vehicle data, battery temperature data, Doppler data, location data, and physical evidence all matter. They are independent data streams, and they all point in the same direction.
She was drunk, she hit him, and she left him.
