A Suffolk Superior Court jury today acquitted John Graham, 19, of Lynn on a charge of first-degree murder for the death of Ciaran Conneely following the annual Irish festival in Adams Corner on Oct. 10, 2011, the Suffolk County District Attorney's office reports.

Prosecutors had charged Graham killed Conneely in a robbery attempt on Nahant Avenue.

The jury did convict Graham for shooting two men, 18 and 20, about three weeks later on Monsignor Lydon Way. He faces up to 20 years for the attempted murder conviction and up to 20 years on each of the attempted robbery convictions in that case, the DA's office reports.
