Rice University officials are continuing their investigation of an accident Thursday afternoon that killed one construction worker and injured seven others.
According to a university news release, the accident occurred when a severe thunderstorm toppled concrete-block walls on the second floor of a new residential college the university is building. The workers were in the process of securing the construction site when high winds knocked the walls over, the university said.
The man who was killed—Juan Romero, of Missouri City, Tex.—was an employee of a masonry firm hired by the project’s general contractor. Four other workers remained hospitalized Sunday, the university said, but none have injuries believed to be life-threatening.
