MEXICO CITY — The death toll in the devastating earthquake that struck Mexico City and surrounding areas three days ago rose to at least 273, as the search for survivors continued Friday.

President Enrique Pena Nieto said 137 of the deaths occurred in Mexico City. He said he believed people could still be trapped alive in a number of buildings following Tuesday’s magnitude-7.1 quake.

Death Tolls Keep Rising in Mexico Earthquake as Rescue Groups Continue Searching

The body of a female teacher was found overnight in the Enrique Rébsamen school in Mexico City, according to media reports. Reports that a girl was found alive in the rubble turned out to be incorrect, even though a Navy commander told cable channel El Financiero that rescuers had been in contact with her.

Many in Mexico became fixed on the alleged girl, Frida Sofía, believed to be 12 years old, who was reported to have been in contact with classmates and was taking shelter under a heavy table.
