An explosion investigation team worked through the morning to collect forensic evidence and assess building damage. The Goldenson Building sustained minor structural harm, though no injuries were reported thanks to the building being mostly vacant at that hour.
Officials emphasized that this was not a random malfunction or lab accident. Instead, investigators are treating it as a criminal investigation involving intentional detonation.
Search for Suspects: Surveillance Photos Released
Authorities have released surveillance images showing two unidentified suspects running from the scene shortly before the explosion. The Boston Police Department is urging the public to assist in identifying these individuals.
The NLP keywords like surveillance photos, suspect identification, and law enforcement agencies are all central to understanding the narrative of this case.
