At about 2:20 PM on Wednesday, July 12, 2017, members of the Boston Police Auto Theft Unit with the assistance of the Massachusetts Environmental Police set up surveillance in the area of Cheney Street in District B-2 (Roxbury) relative to an ongoing investigation into the theft of motor scooters in several Boston neighborhoods.
During their surveillance, officers observed two males who were known to them as 19-year-old Jacari Cosgrove and a 17-year-old juvenile from Dorchester operating motor scooters and dirt bikes recklessly and without licenses in the area of Elm Hill Ave and Homestead Street. Officers maintained surveillance and eventually the males were joined by a third male, another 17-year-old juvenile from Dorchester also known to officers as unlicensed, in the area of Cheney Street. Officers observed Cosgrove enter a residence on Cheney Street and return with a pair of bolt cutters before mounting the back of a blue and white dirt bike as a passenger. The three suspects then took off on the two motor bikes onto Walnut Street and drove toward Mass Ave and Boylston before officers lost sight of them. Through the officers’ training and experience, they believed the suspects were about to commit a theft of a scooter.
Approximately half an hour later, officers observed the three suspects return to Cheney Street, this time with Cosgrove operating a third red scooter with bolt cutters still in hand. Officers concluded that a theft had occurred and began to walk toward the rear of the residence. As they approached, officers observed Mr. Cosgrove attempting to cut the lock on the seat of the red scooter. Further investigation revealed that the vehicle had just been stolen from the area of 699 Boylston Street. Officers also determined that the two 17-year-old juveniles were also operating stolen motor bikes.
Officers arrested Cosgrove and charged him with Larceny of a Motor Vehicle, Possession of Burglarious Tools, Negligent Operation, Prohibited Operation of a Recreational Vehicle, and Operating a Motorcycle without a License. The first 17-year-old juvenile was arrested and charged with Larceny of a Motor Vehicle, Receiving Stolen Property, Negligent Operation, Operating a Motorcycle without a License, and No Registration Plate. The second 17-year-old juvenile was arrested and charged with Larceny of a Motor Vehicle, Possession of Burglarious Tools, and Operating a Moped without a License.
