The medical examiner said the seven victims died from either blunt trauma or smoke inhalation and classified their deaths as accidents. Results were still pending on the eighth victim.
Con Edison crews discovered an alarming natural gas concentration near the scene of the deadly East Harlem building explosion this week, a National Transportation Safety Board member said Friday.
Eight people are now confirmed dead in the blast that also injured more than 60 others. Others are still believed to be missing.
Investigations into the East Harlem explosion have been launched by the Fire Department of New York, Con Edison, as well as the National Transportation Safety Board.
