A man driving around in a Kia Sportage "full of tools stolen from a business" and discussing plans for a future heist with accomplices accidentally pocket-dialed 911 on his phone, allowing the police to listen in and, eventually, arrest him.
The Onondaga County, N.Y. Sheriff's Office were, in fact, already looking for a suspect in the robbery when the cell phone decided to turn in its owner; the dispatcher, realizing what was going on, "relayed the conversation to deputies," and soon a sheriff's deputy pulled over the Sportage. The call was still connected when the deputy asked for license and registration.
Which means, among other things: Trend alert! Last week, a house called 911 for help; so we're only one more allegedly-accidental-but-actually-quite-helpful emergency services call away from there being a "thing." Also, there is a lesson here—turn off your phone when you are planning a robbery.
