MONTERREY, Mexico — Emergency personnel are using cranes and abrasive cutters to remove slabs of concrete at a collapsed shopping mall in northern Mexico in hopes of finding the last missing construction workers.
Three levels of the mall collapsed Thursday, killing at least seven men. Nuevo Leon state civil defense official Miguel Perales says "They literally sandwiched."
Perales said Friday that rescuers using sonar equipment, dogs and heat-image cameras had detected signs of a person or a body at three different sites in the rubble in the industrial hub of Monterrey.
Fifteen people were injured, and all the victims are believed to be construction workers.
Work on the three-story structure was being carried out without the necessary licenses.
