About

Det. Lt. Brian Tully commanded the Norfolk State Police Detective Unit and supervised the state-police investigation into John O'Keefe's death. His Trial 1 testimony covered the January 29 search of the Fairview Road snowbank, the decision to exclude Canton Police because of conflicts, cell-site location data, and surveillance video. He also addressed the decision not to search the interior of the Albert home; Trooper Michael Proctor served as case officer.

Key Points

  • Tully explained that Canton Police were removed from the investigation because the homeowner at 34 Fairview Road, Brian Albert, had connections to Canton PD — a conflict the MSP acknowledged and acted on before the investigation concluded.
  • On the January 29 snowbank search, Tully described the recovery of taillight pieces and John O'Keefe's missing shoe within a five-foot area, physical proximity the prosecution used to anchor its vehicle-impact theory.
  • Tully walked the jury through cell tower ranging data and surveillance footage showing a black SUV — consistent with Read's Lexus — near the Albert house at 12:15, 12:27, 5:11, 5:15, and 5:18 a.m., and noted that Read made 53 unanswered calls to O'Keefe's phone between 12:33 a.m. and 6:03 a.m.
  • On cross, Tully conceded that his official report stated three pieces of plastic were recovered when the evidence bag handwritten notes indicated a different count — an inconsistency he acknowledged but defended by pointing to the contemporaneous bag labeling.
  • Jackson presented a conditional calculation that, if the two RTT arcs represented sequential phone positions 0.004 seconds apart, would imply a device speed of 135,000 miles per hour. Tully agreed with the arithmetic and that such travel would be impossible for a cell phone, but rejected the sequential-position premise and said he was not suggesting the phone traveled at that speed.

Highlights (1)
Quote

“The times were not part of the depiction of the range. I will suggest to you that it is probably unbelievable that those are actually start and end times. What I am saying is we don't know for certainty that that is the exact time of the first distance and the last distance. I'd have to look back at the records.”

Tully qualified the relationship between the Verizon times and the distances used in the range depiction.
