Public works employees called to the scene of a sinkhole just north of Miami, Florida quickly found an electrical cord in the ditch. Turns out the, sinkhole was actually an unfinished 150-foot-long tunnel to a bank across the street. From the New York Times:
F.B.I. investigators found that the tunnel had a diameter of about 3 feet and opened up into a wooded area, Special Agent Michael D. Leverock said in an interview on Wednesday evening. It was so narrow that a person would have to lie on his or her stomach to navigate it, Agent Leverock said.
No one got into the bank, and no money was stolen, Agent Leverock said…
"Everybody here is just shaking their heads," he said. "They could've been going for the A.T.M., they could've been going for the vault." But after the would-be bank thief reached the ultimate destination, Agent Leverock speculated, then what?
Inside or near the tunnel, investigators found a wagon that had likely been used to haul dirt, as well as a power generator and a winch, which can be used to haul heavy loads, according to an F.B.I. news release.
