Six people, including a mother and daughter who died in a small plane crash in Philadelphia, have been identified by the company that operates the medical transport jet.
The seventh unnamed victim was on the ground at the time of the crash.
Philadelphia Mayor Sherrell Parker announced Sunday that the injury count reached 22, with five still in hospital, three of whom are in critical condition.
The cause of the crash is not yet known, but investigators recovered the aircraft's black box on Sunday, said in a statement obtained by CBS, the BBC's US news partner.
A spokesman for Jet Rescue Air Ambulance revealed the identity of the victim to CBS. All were Mexican citizens, including children on board who were traveling to get medical treatment.
The spokesman said the victims were Captain Alain Alejandro Montoya, Copilot Jos de Jesus Juarez Juarez, Dr. Raul Meza Aredondo, Rodrigo Lopez Padilla, Valentina Guzman Murillo and Lizes Murillo. I identified him as Ozuna.
Friday's crash was just a block from Roosevelt Mall, a three-storey shopping center in a densely populated area of Philadelphia, the fifth-largest city in the United States.
The area is packed with terraced homes and shops. Many properties lost power after crashing.
Authorities were still assessing the extent of damage to residential areas.
They were not sure how many individuals had evacuated, but city officials confirmed that 11 of the property had been severely damaged.
The average number of shelters installed at local high schools per night is 6 or fewer than the number of people per night, officials said. Several businesses were also affected.
While some streets around the crash site remain closed, Philadelphia Police Commissioner Kevin Bethel said several lanes could begin traffic on Monday.
The fatal conflict is being investigated by the NTSB and the Federal Aviation Administration with support from other local agencies.
NTSB officials say a preliminary investigation revealed that the flight would rise to about 1,500 feet before entering a steep descent, resulting in greater impact.
The entire flight was less than a minute, they said.
Investigators discovered two engines, but no black boxes on the aircraft were found.
Mayor Parker said investigators are “considering all available material.”
Residents are asked to report any debris found in the area.
