Two vehicles were stolen Wednesday in Southbury, and the thefts are connected.  Southbury Police responded to the post office after a woman reported her car was missing.  The vehicle was left running with the doors unlocked when she went into the post office.  The car was driven about 4 miles away to a daycare center on Southford Road where a second vehicle was stolen.  That car was also left running with the doors unlocked.  The original stolen vehicle was located. Southbury Police are currently looking for a black 2016 Porsche Cayenne bearing Connecticut registration AU71871.  Officers reminded residents to shut off their vehicles, take the keys and lock their cars when they're unattended.  Anyone with information about yesterday's crimes is asked to contact Officer Markette at (203) 264-5912.
