The accident happened just before 10 a.m. today. Division chief Michael Cox of the Anne Arundel County Fire Department says a 30-foot by 40-foot concrete wall, weighing about 25 tons, fell on the two workers.
"The wall was in an upright position," Cox says. "We do know that the victim that received the fatal injuries was working from a lift at the time that the wall fell, while the other victim was in the general vicinity on the ground."
The worker who died, described as a male in his late twenties, was pronounced dead at the scene. The other man, said to be around 35 years of age, was taken to a Baltimore hospital.
Cox says investigators are still unsure what caused the wall the fall. The casino, called Maryland Live!, will have more than 4,700 slot machines. The first portion is scheduled to open at the end of next year.
