About
Jennifer Hammers testified for the prosecution on Day 40 about Krystle Marie Campbell's autopsy, which she performed on April 16, 2013. A forensic pathologist, she classified Campbell's death as homicide and attributed it to blast injuries to the torso and lower extremities. She explained that damaged blood vessels in Campbell's lower legs caused fatal blood loss.
Hammers described deep wounds, a complete femur fracture, smaller foot fractures and a back burn that appeared third-degree. She also described recovered flat metal pieces, pellets and silicone-type material. The court admitted six photographs and five physical exhibits, noting the defense's prior objection to autopsy photographs. Her testimony addressed the physical mechanism of death, not the identity of the person responsible.
During William Weinreb's examination, the defense challenged the disclosure and foundation of a proposed survival-time opinion. David Bruck argued at sidebar that the estimate was speculative and inflammatory, including uncertainty about loss of consciousness. The court permitted the opinion as consistent with the disclosure that death was not instantaneous. Hammers then gave a qualified estimate of seconds to approximately a minute and explained how vessel size affects blood-loss timing. The defense declined to question her.
