STEVE INSKEEP, HOST:
Good morning. I'm Steve Inskeep. It's common to discover a sinkhole in Florida. What was in this hole is not. Pembroke Pines utility crews responded to a hole in a road, and a worker discovered a power cord in that hole. The FBI determined the sinkhole had exposed a tunnel 2-to-3-feet-wide. The entrance began in some woods which had a winch, generator and digging tools. And the tunnel was pointing toward a nearby bank for an apparent robbery attempt.
