New London resident Maurice L. Milligan, 36, a suspect in an April 2013 shooting in the city, was sentenced Friday to 90 months in federal prison for illegally possessing a firearm, according to the office of U.S. Attorney Deirdre M. Daly.

Police said the shooting was reported about 11:35 p.m. on April 22, 2013, in the area of Ocean Avenue and Evergreen Street. Officers found several 9-mm shell casings at the scene. A review of surveillance video from the Sam’s convenience store showed Milligan and an unknown male exchanging words before the reported shooting. Police said that Milligan was seen walking in the backyard of 54 Sherman St. with an object in his hands a few seconds after the shooting.

Three days later, while on patrol, police spotted Milligan and his friend Travis Gee in a black Nissan. Police informed both Milligan and Gee that they believed they were involved in Monday’s shooting. Police asked Milligan if he was in possession of a gun, which he denied. When police asked Milligan to step out of the car, he was wearing a bulletproof vest.

Police found a Glock 9-mm handgun underneath the front driver’s seat. Milligan told police that he did not know the gun was in the car and could not say why he was wearing a bulletproof vest.

A ballistics comparison made of the shell casings recovered on the night of April 22 with the Glock seized from under the driver’s seat of the car Milligan was driving on April 25 established that the Glock was the weapon that fired the shots, according to the U.S. Attorney’s office.

Prior to April 2013, Milligan had been convicted in the Queens County (N.Y.) Supreme Court of third degree criminal possession of a loaded firearm and second degree robbery.

Milligan has been detained since his arrest on April 25, 2013. On June 23, 2014, he pleaded guilty to one count of possession of a firearm by a previously convicted felon.

The case was investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, the New London Police Department and the Office of the State’s Attorney for the Judicial District of New London. The case was prosecuted by Assistant U.S. Attorney John H. Durham.

In addition to the 90 month prison sentence, Judge Vanessa L. Bryant imposed three years of supervision upon Milligan’s release. Milligan also has pending cases in New London Superior Court, where his next court date is scheduled for March 5.
