The Suffolk County Grand Jury this week returned an additional indictment against a rabbi who once lived in Brighton and is already accused of sexual assaults on two young students during the 1970s, Suffolk County District Attorney Daniel F. Conley said.

Wednesday’s indictment is the fifth to charge STANLEY Z. LEVITT (D.O.B. 4/4/46) of Philadelphia with indecent assault and battery on a child. He is expected to be arraigned on the new complaint in the Magistrate’s Session of Suffolk Superior Court on June 30.

The grand jury late last year indicted Levitt for four sexual assaults he allegedly committed on two boys who were about 11 years old at the time. One charge arises out of a May 1975 incident in which Levitt allegedly visited a student who was recuperating at Children’s Hospital in Boston after an accident. The other three offenses were allegedly committed against a different male student during a three-night visit to Levitt’s Chiswick Road home, also believed to have taken place in 1975.

The third victim came forward to prosecutors after reading media accounts of the earlier cases. Like the other victims, he was a sixth grader at the Brookline school that had employed Levitt in the mid-1970s.

Finding that many young victims of sexual abuse were unable or unwilling to speak about their experiences for many years, Conley spearheaded efforts to lengthen the statute of limitations for sex crimes against children. In 2006, those efforts paid off when the statute of limitations on child sexual abuse was extended from 15 years to 27 years.

It was a different aspect of the law, however, that allowed prosecutors to pursue the charges against Levitt, Conley said: when Levitt left Massachusetts for Pennsylvania a few years after the abuse, the clock on the statute of limitations stopped.

Assistant District Attorney Wayne Margolis of Conley’s Child Abuse Team led the grand jury investigations that led to the indictments. Philip Harrison is the DA’s victim-witness advocate assigned to the case. Attorney Scott Curtis represents the defendant.
