JOHANNESBURG (AP) — Search teams finished checking a derelict Johannesburg apartment building a day after one of South Africa’s deadliest fires broke out there as pathologists faced the grisly task Friday of identifying charred bodies and body parts that were transported in large trucks to mortuaries across the city.

The death toll from Thursday’s predawn blaze rose to 76 after two people died in a hospital overnight, Health Minister Joe Phaahla told reporters. At least 12 of the victims were children, authorities said.

Homeless South Africans, poor foreign migrants and others who found themselves marginalised in a city often referred to as Africa’s richest but which has deep social problems inhabited the downtown building.

The number of injured people hospitalised from the fire also increased to 88, according to a provincial health official.

After conducting three searches through each of the building’s five stories, emergency services personnel believed that all human remains were recovered from the site, Johannesburg Emergency Services spokesperson Nana Radebe said.

Police and forensic investigators took over the scene for their own examinations, Radebe said.

The remains of some of the victims were taken to a mortuary in the township of Soweto, in the southwestern outskirts of South Africa’s economic hub, where people began to gather as authorities called for family members to help identify the dead.
