The final defendant convicted in a deadly New Jersey schoolyard attack has been sentenced to 195 years in prison.

Gerardo Gomez was one of six men and boys who pleaded guilty or were convicted in the execution-style murders of three college-bound friends in a Newark school playground in 2007.

A jury convicted Gomez last November on multiple counts including robbery, murder and attempted murder.

Attorney Michael Robbins had argued at the sentencing Wednesday that Gomez, who was 15 on the night of the murders, should receive a shorter sentence because of his age and because he didn't wield a knife or gun used in the attacks.

Four other defendants are serving multiple consecutive life sentences. The fifth received 30 years in exchange for his testimony.
