Crews tore down most of the Florida home Sunday over a giant sinkhole, after deeming it too dangerous to keep searching for the man swallowed up from his bedroom, NBC News reported. Authorities plan to continue the demolition on Monday. Rescue workers on Saturday called off their search for 36-year-old Jeffrey Bush, who had not been heard from since the hole appeared at about 11 p.m. ET Thursday in Seffner, near Tampa. “Unfortunately we have not been able to determine the whereabouts of Mr. Bush,” Hillsborough County Administrator Mike Merrill said. “With all the equipment that we brought in and specialized help, we have just not been able to locate Mr. Bush, and so for that reason the rescue effort is being discontinued.” At least 30 feet wide and 50 feet deep, the sinkhole is growing and is posing a safety risk to the residence next door, officials said. A 100-foot safety zone was set up around it Friday and homes near the hole were evacuated for fear of a sudden collapse.
