A Salem resident was able to capture Saturday's bright flash and loud boom on video.
Salem's latenight "mystery explosions" have become something of a local conversation piece. Every couple of weeks, our Facebook and Twitter page will light up with messages from city residents who want to know what caused that earth-shattering sound in their neighborhood so late at night. The latest report was in the early hours Saturday morning, when residents in Marblehead and Salem called 911 to report hearing what sounded like a firework or gunshot in their neck of the woods. Police received similar reports at 12:22 a.m. on Nov. 19, when residents reported a loud boom in the area of Bridge Street. A big thank you to Derek B, who sent in the video above, which he captured on home surveillance equipment.
