The death toll in the Harlem explosion that leveled two East Harlem buildings March 12, has risen to seven, according to officials.
Rescuers sifting through the debris of the two buildings that housed apartments, a piano business and a church, discovered a seventh victim early Thursday as they continued searching for more missing people.
Fire Department spokesman Danny Glover said Thursday morning the body was the fourth found overnight, according to USA Today.
