A worker at a construction site was killed by a truck during the night as he slept in an area open to vehicles, the Beijing Times reported on Tuesday. The man, surnamed Feng, 20, was sleeping outside one night in April because his dormitory was hot and full of mosquitoes, the report said. He was killed at about 4 am by a truck that was delivering sand to the site. The truck driver was arrested and will be tried for negligence.
