This is one of those... "Is this real life?" stories. Deputies in Oregon responded to a possible burglary call. The woman reported that a stranger was in her bathroom, the door was locked but she could see shadows under the door.
So... deputies respond and surround the house, where they could hear a "rustling" noise in the bathroom. They used their loudspeaker to command the intruder come out. After 10 minutes of no response, they went in- guns drawns...
Only to find...
A ROOMBA vacuum cleaner... and a very clean floor. They later announced the "crime" on their Facebook!
