Assistant Prosecutor Cheryl Cucinello is telling a jury in Newark that Lee Evans has long been suspected and is responsible for the teens’ deaths.
The bodies of the five boys, initially declared missing in 1978, were never found.
Their disappearance became one of New Jersey’s longest running cold cases.
Evans, who is representing himself against the murder charges, said earlier Friday during his closing statements that there is no evidence to connect him to the case.
The state’s main witness testified during the trial that he and Evans lured the boys to a vacant home, trapped them in a closet and set it ablaze in retaliation for the teens stealing some marijuana.
