Zeng Guang Lin, a 20-year-old construction worker, was on a scaffold and installing metal siding on a building when he was asked to go to the roof to assist with a different job. Lin went to the roof wearing his safety harness but was unable to find a place to tie off. While Lin was on the roof he fell about 20 feet to the ground.
He suffered multiple, severe injuries including a closed-head injury, spinal fractures at L1-5, fractures to his scapula and several ribs, internal injuries, including a renal hematoma, a lung contusion and a lacerated spleen. He also suffered cervical and lumbar disk herniations.
Because of the closed-head injury, Lin developed encephalomalacia, which is the degeneration of the brain tissue resulting in memory loss, motor problems and impaired thought-processing and other cognitive functions. He is permanently disabled.
