The identities of three construction workers killed in that scaffold collapse in West Campus were released Friday.

Wilson Joel Irias Cerritos, 30, and Jesus Angel Lopez Perez, 28, were both from Honduras. Raudel Ramirez Camacho, 27, was from Mexico.

The men fell when a scaffold gave way outside the 21 Rio building's 11th floor Wednesday afternoon. A fourth man jumped from the scaffold as it started to fall. He suffered only minor injuries.

Federal investigators have stopped construction at the site until they figure out what went wrong.
