State police have now arrested three out of four people in connection with the theft of a state trooper’s rifle in March.

The theft took place at approximately 4:50 a.m. in north Milford, where a number of cars, including a Connecticut state trooper’s car, were broken into.

Among other items, a Connecticut State Police AR-15 rifle with two fully loaded magazines and a bulletproof vest were stolen. Detectives from Connecticut State Police Central District Major Crime responded to the scene and assumed the investigation.

In conjunction with the New Haven Police Department Criminal Intelligence Unit, the ATF, and the FBI Safe Streets Gang Task Force, the Connecticut State Police CDMC developed a suspect, Travis D. Ingram. They secured a total of seven firearms and larceny related felony arrest warrants from the Milford and New Haven Superior Courts for him and three other individuals for offenses that occurred in New Haven and Milford.

The AR-15 rifle, two magazines, and bulletproof vest were recovered soon after they were stolen, police said.

In early July state police detectives and the New Haven Police Department Criminal Intelligence Unit located Ingram, 20, of New Haven and took him into custody.

They later arrested Leandre Crockett, 18, of Hamden, and then James Lee, 19, of New Haven.

The three were charged with a list of violations, including stealing a firearm and possession of an assault weapon.
