DARIEN — A car was stolen and several vehicles entered over the course of several days as a result of people leaving their keys in unlocked cars, police said.

On Aug. 19 around 4 a.m., a resident on Rocaton Road left his house, leaving behind his yellow 2005 Nissan Xterra in the driveway with the keys in the cup holder of the center console. When he returned home about two hours later, the Nissan was missing. Police searched the area but did not find anything and are continuing to investigate.

The next day, a failed attempt at stealing a 2016 Honda Pilot led the police to discover several more car break-ins in the area of Hollow Tree Ridge Road.

On Aug. 20 around 12:30 a.m., a resident on Hollow Tree Ridge Road awoke to a loud banging noise. When they looked outside, they saw someone had driven their white Honda Pilot into their garage door. The driver’s side door was ajar and the keys, which had been in the car, were missing.

The owner called 911 and officers, including the K-9 unit, responded. Police determined someone had attempted to steal the car, but put the car into drive instead of reverse.

Although officers could not locate the person responsible, while canvassing the area, police found several other cars had been entered on the street. All were unlocked, but nothing was taken.

On nearby Wilson Ridge Road, however, two debit cards were taken from an unlocked Mazda and a driver’s license, debit card and credit were taken from two unlocked cars at another home.

Police had received similar break-in reports several days earlier.

On Aug. 14, a Tulip Tree lane resident said he entered his unlocked Ford Escape and found the glove box open. He thought he had left it like that until his neighbor reported a briefcase, which was previously in his car, was in her yard. A laptop was missing from the briefcase.

On Aug. 18, a woman went to police headquarters and said $130 was missing from her BMW, which she’d left unlocked in the driveway of her Dubois Street home overnight.

Police searched the neighborhood in both instances, but found nothing. Investigations are ongoing.
