Chinese officials have given journalists a tour of a collapsed mountain of construction waste in a leading manufacturing city to display their handling of the search for 76 missing people, as questions build up about why they didn't act months earlier to prevent the disaster.

Rescuers pulled out the first body Tuesday buried by Sunday's mudslide from a construction dump site in the city of Shenzhen.

Vice Mayor Liu Qingsheng told a news conference that 76 people are still missing. He said the number had declined as people initially unaccounted for have gradually appeared.

State media reported that the district government which covers the area had identified problems with the construction dump months earlier.
