WCVB reports a State Police cruiser stolen from a state lot on D Street South Boston this morning showed up, abandoned, around 12:45 p.m. at Twin City Plaza in Somerville.

On the Arlington List, a Facebook group for residents of that town, one resident reported an odd occurrence around noon:

A few minutes ago, a state police cruiser (one person in the vehicle) stopped asked me where is Davis Square, or Somerville, or Cambridge, while I was watering our garden near Park Circle. It is strange to me that a police has to ask me for directions. It raised a flag for me...

And, yes, all you grumpy cranks who assume every last person who posts something on the tweeters and the MyFaces is a moron, the resident did report the incident to police, so save yourself some keystrokes before fulminating in the comments here.
