A District man was sentenced to 15 years in prison Monday for a shooting last year at a birthday cookout that left three people injured.

D.C. Superior Court Judge William M. Jackson sentenced Antonio Nero, 32, in connection to the April 18, 2010, shooting at the cookout in the 1100 block of Morse Street NE.

According to prosecutors, Nero and some 50 family members and friends were holding a cookout for one of Nero’s family members when three men arrived in a nearby alley, two to sell drugs to a friend of Nero’s.

An argument broke out during the deal, prosecutors said. Nero then shot one man as he stood next to a car, chased a second down the alley and shot him and shot the third as he tried to flee in his car.

In May, a jury found Nero guilty of assault with a dangerous weapon, mayhem while armed and other offenses.
