Police discover hidden underground tunnels used by the homeless
By Eric Pfeiffer, Yahoo! News

Kansas City Police Officer Jason Cooley, who was leading an investigation of stolen copper wiring from a nearby grain mill.

While checking on the seemingly ordinary homeless campsites, Cooley discovered a series of tunnels that went several feet under the earth and stretched nearly 25 feet.

After discovering the tunnels, a police robot was used to further investigate the underground dwellings. Once police were able to confirm no one was inside them, they brought in a tractor to fill in the tunnels.
