About

Brian Tully described his supervisory role in the investigation of John O’Keefe’s death. He said Canton police provided support rather than leading the investigation because of an appearance of conflict involving a Canton officer’s relationship with the homeowner at 34 Fairview Road. He testified about the search outside the house, where a sneaker and red and clear plastic pieces were recovered, and about how the evidence was documented and stored. Defense counsel questioned why investigators did not seek consent or a warrant to search inside the house. Tully said they had no basis to do so. He acknowledged that his later report did not accurately document the plastic collection, but said the contemporaneous evidence-bag notes and his memory were more accurate. Tully also described surveillance footage showing black SUVs he considered consistent with Karen Read’s vehicle and explained that cell-site records indicated a phone’s general area, not its exact location. When defense counsel used his range maps to propose a travel-speed calculation, Tully accepted the arithmetic under the stated premise but disputed that the records showed the phone moving between those mapped distances in that interval. He said he would need to review Verizon’s records key to determine whether the listed times marked the first and last distances.
