At least seven people were killed in Wednesday's gas leak explosion in East Harlem, the fire department said on Thursday.
Police confirmed that the deaths include four men and three women.
Authorities identified Griselde Camacho, 44, Carmen Tanco, 67, and Rosaura Hernandez-Barrios, 21, as among those who died.
The names of four additional people found overnight have not yet been released.
The blast occurred near 116th Street at about 9:30 a.m. causing two buildings, 1644 and 1646 Park Ave. to collapse. Dozens were injured, including at least three children, and at least five people are still missing.
"This is a tragedy of the worst kind because there was no indication in time to save people," Mayor Bill de Blasio said on Wednesday.
Con Edison said on Wednesday that it received a call at 9:13 a.m. about a gas odor in the area and that its crews arrived at the scene just after the explosion.
The National Transportation Safety Board, which oversees pipeline safety, said it is investigating the blast, including Con Edison's response to the gas leak.
