The earth opened up behind a one-story home in Florida late last night, swallowing an entire bedroom into a sinkhole—now 100 feet wide—and likely killing one. Authorities say that their equipment has been unable to find signs of life, meaning that the 36-year-old man who was sucked into the rubble is believed dead; according to early reports, the victim's brother attempted to rescue him, only to himself require rescue by an arriving sheriff's deputy. "It sounded like a car hit my house," Janell Wheeler, the man's aunt and one of the occupants of the home, told the Tampa Bay Times. The sinkhole, which expanded from 30 to 100 feet wide overnight, is reportedly still developing; its causes are unclear, though it's not man-made. [Tampa Bay Times | CNN | Sheli Muniz]
