Massachusetts State Police Trooper Joe Paul, a crash expert who worked on the case, returned to the stand on Monday. The defense argues that the accident reconstructionist has "confirmation bias," and that he was told what happened when he got to the scene, and that he looked for evidence to support that conclusion.
The prosecution argues the evidence clearly indicates a pedestrian strike.
Paul said O'Keefe was struck by Read's SUV, which was traveling in reverse at up to 24 mph and that O'Keefe was "projected" more than 30 feet.
On cross-examination, defense attorney Alan Jackson challenged Paul's qualifications and the formulas used in the calculations that enabled him to reach his conclusion.
He questioned Paul about a cocktail glass and cellphone that were found near O'Keefe.
"The cellphone was found under his torso, under his body. What is your theory on how that cellphone ended up flying 30 feet?" Jackson asked.
"It just did," Paul said. "It just did. That is the evidence at the scene. I didn't put the evidence there."
Paul told the jury he does not know where the phone had been prior to the collision. The defense argues that the damage to Read's SUV and injuries to O'Keefe are not consistent with a pedestrian strike, but rather a fight inside the house.
Read is accused of killing her boyfriend, a Boston police officer, by striking him with an SUV and leaving him to die in a snowbank.
