Lingzi Lu

Lingzi Lu's death outside the Forum restaurant was addressed through eyewitness, emergency-response, and medical testimony. Her friend and Boston University classmate Danling Zhou identified photographs of them immediately before the second explosion, described seeing Lu's thigh injury afterward, and recalled seeking news of her from the hospital before learning she had died. Dr. James Bath described using belt tourniquets to control Lu's bleeding and requesting CPR as her breathing deteriorated. Officer Lauren Woods described clearing her airway and continuing chest compressions. Medical examiner Katherine Lindstrom attributed Lu's death to blast injuries of the lower extremities, explaining that severed left femoral vessels caused rapid blood loss. She estimated death within seconds to minutes, described the injuries as very painful, and said continued consciousness was possible, not certain. Autopsy photographs and recovered metal fragments were admitted. The jury's death-result findings for offenses involving the second pressure-cooker bomb named Lu and Martin Richard.

During the penalty phase, Jinyan Zhao, whom Lu treated as an aunt, testified about their relationship and the effect of Lu's death on those close to her. Photographs and a translated recording of her father's memorial speech were admitted, and the recording was played. In a separate evidentiary ruling, the court required victim-photo montages, including Lu's, to be disassembled into selected individual images to limit cumulative emotional impact, while permitting her father's eulogy to be played as-is.
