DARIEN — Two cars were stolen and more were entered as part of a continuing trend involving unlocked cars in Darien.

During the overnight hours from April 4 to April 5, numerous unlocked cars were entered on Shields Road, Kona Road, Libby Lane and Wakemore Street. Many of the owners reported nothing missing but found their cars had been rifled through.

Police discovered the break-ins when a white 2017 BMW X3 was reported stolen from a home on Shields Road around 5 a.m. The owner had last seen the car around 10 p.m. the night before and had left the vehicle unlocked with the keys in the center console.

Using the car’s GPS system, police were able to track the vehicle to Waterbury. Around 7:45 a.m. Waterbury police recovered the car in good condition.

While investigating the missing car, police checked a 2017 Toyota Highlander left unlocked in the same Shields Road driveway. A black leather wallet containing a license, three credit cards and $70 in cash was taken, as well as keys and a key ring valued at $70.

While searching the street, police found another car had been entered with nothing taken and another neighbor had heard car doors opening and closing around 4 a.m.

On Kona Road, three cars were rifled through after being left unlocked overnight and $20 was taken from the glove box of an unlocked Volvo.

Across town, a woman on Wakemore Street reported that $500 Beats headphones and a book bag with personal papers were taken out of her unlocked Jeep Wrangler. The book bag was later recovered on the woman’s lawn.

Three days later on April 8, three cars parked in the driveway of a home on Roland Drive were entered. The cars were left unlocked and an iPhone charger was stolen from a 2003 Chevrolet Tahoe.

The next day and one street over, an Oak Crest Drive woman reported her white 2011 Porsche Cayenne S — worth $50,000 — was missing after she left it unlocked in her driveway with the keys inside overnight.

Police searched the neighborhood and found no one had seen or heard anything overnight, but there had been been other car break-ins in the area potentially connected to the theft.

Police are continuing to investigate these incidents.
