Day 41 of 67
Appearing:

The government rested after medical testimony about Lingzi Lu and Martin Richard and examination of bombing-scene imagery. The defense presented search evidence and digital-record analysis, with witnesses acknowledging limits on timing and location conclusions. The Rule 29 motion and proposed defense evidence remained unresolved.

Full day summary

Katherine Lindstrom testified that Lingzi Lu died from blast injuries causing rapid blood loss and classified the death as homicide. She estimated death occurred within seconds to minutes and said Lu possibly remained conscious until death. The court admitted autopsy photographs and recovered metal evidence, warning jurors that the photographs were graphic. FBI field photographer Michelle Gamble compared Forum surveillance footage, photographs, receipts, and phone records. Her 20-second video adjustment depended on the race clock being accurate. On cross-examination, she acknowledged that recorded call duration began with dialing and did not establish conversation length. She clarified that the location chalk depicted a minute before the second explosion and omitted nearby people at the prosecution's direction. She corrected a photograph's time to 2:49 p.m. and said she had not measured the defendant's distance from the blast. Henry Nields described Martin Richard's fatal blast injuries and concluded that death resulted principally from blood loss, with homicide as the manner of death. He qualified some recovered-fragment identifications as consistent rather than certain. Clothing, fragments, and autopsy photographs were admitted. The defense questioned neither medical examiner. The government rested, and the court reserved decision on the defense's Rule 29 motion. The defense recalled Gamble about searches. A wiring book and its photograph were admitted, although she did not remember the book; the court excluded a proposed recovery-list excerpt. Defense investigator Gerald R. Grant, Jr. then analyzed tweet timing, university card records, and cell-site activity. He associated January 31 phone activity with towers around UMass rather than Saugus and found no indication that the phone left the Dartmouth/New Bedford area during March 6 purchases in New Hampshire. Cross-examination established that these records did not identify the phone's user or precise position, or establish whereabouts between card entries. After the jury left, counsel disputed proposed computer evidence and boat-exit photographs. The court deferred those issues, left the Rule 29 motion pending, denied a motion concerning an admission by a party opponent, and set Monday the 6th as the working date for closings and instructions.

3. Michelle Gamble — Cross/Redirect/Recross (Part 2)

Michelle Gamble’s cross-examination and follow-up questioning addressed photograph timing, omissions from her location diagram, and movement around the explosions. Her testimony concluded before the morning recess.
