News 4 has obtained surveillance footage of an explosion in Soulard that killed three and injured four others.
The footage, which was captured by a surveillance camera at a nearby BP gas station at 7th and Russell, shows the initial explosion at the Loy-Lange Box Company at 7:32 a.m. Monday.
Debris from Loy-Lange then shot up in air. The footage then shows that a giant piece of a boiler that launched into the air from the Loy-Lange building was airborne for 11 seconds before it crashed through the roof of the Faultless Healthcare Linen building.
Firefighters said one person from the Loy-Lange building and two from the Faultless Healthcare Linen Building were killed.
