  "description": "Day 17 centers on two forensic scientists from the Massachusetts State Police Crime Laboratory. DNA analyst Andre Porto testifies that O'Keefe's DNA was found on the passenger-side tail light of Read's vehicle at overwhelming statistical ratios, and that O'Keefe's own clothing yielded single-source profiles — while cross-examination reveals investigators never requested comparisons against individuals central to the defense theory, including Canton police detectives Kevin Albert and Kenneth Berkowitz. Trace analyst Ashley Vallier then walks the jury through physical match analysis establishing that plastic debris from multiple evidence bags collected at 34 Fairview Road mechanically fits the tail light housing from Read's vehicle, with a small plastic fragment also recovered from O'Keefe's clothing. Yannetti's cross of Vallier exposes a six-week gap between the incident and evidence submission to the lab, with Trooper Michael Proctor as the sole handler throughout. In a midday procedural session, Judge Cannone rules against the defense's motion to exclude or delay Shanon Burgess's updated clock drift analysis, though she grants the defense extensive cross-examination latitude and a limited rebuttal through Dr. Welcher.",
