Robert Costanzo

Robert Costanzo, a Pembroke firefighter and paramedic, testified for the Commonwealth on Day 3 about treating Lindsay Clancy on January 24, 2023. He found her breathing but unresponsive, already secured to a backboard with a neck collar. Her wrists were bandaged, and he described visible neck lacerations as superficial, without active bleeding. Responders placed two IVs and administered two milligrams of Narcan during transport because she was unresponsive with constricted pupils. He described increased agitation afterward, but no full awakening or verbal communication.

On cross-examination, Kevin Reddington questioned both the treatment response and the limits of Costanzo's assessment. Costanzo maintained that reaching and grabbing increased after Narcan, while agreeing that a head injury could be consistent with that behavior. He said his Narcan training concerned opioids, not benzodiazepines. He acknowledged leaving the wrist bandages in place, viewing the neck only through collar openings, and never seeing it after collar removal. He did not know about the spinal fractures, hemorrhaging, or rib fractures asserted in counsel's questions; his answers did not establish those injuries.

On redirect, Costanzo distinguished approximately seven minutes in the dark backyard from 18 minutes with Clancy in a lit ambulance. He denied seeing blood seep through the wrist bandages or pool around or flow from the neck. His testimony addressed visible bleeding and treatment observations, not a complete assessment of injury severity. The defense asked no further questions, and the judge excused him.
