SILVER SPRING, Md. (AP) — Police in Maryland say a seventh body has been found in the debris of an explosion and fire in an apartment complex.
Montgomery County Police said in a news release that the body was found Tuesday in one of the buildings.
On Wednesday, the National Transportation Safety Board said it has started an investigation into the cause of the explosion.
The agency says investigators from the Office of Railroad, Pipeline, and Hazardous Materials Investigations have been on scene of the incident since last week.
The explosion on Aug. 10 in Silver Spring sent debris hundreds of feet, and people more than a mile away reported the blast was strong enough to shake their homes. More than 30 people were injured, including three firefighters.
Police have not identified those killed.
