MARBLEHEAD — A Salem Superior Court judge has scheduled a trial for June 10 in the case against a private youth hockey coach in Marblehead charged with sexually abusing eight boys in Essex County. 

Christopher Prew, 32, of Winthrop, was also arraigned Friday in a case involving a Canadian child whom he allegedly molested during a youth hockey exchange trip to Marblehead. He pleaded not guilty. 

Prew, who is also facing charges involving a ninth boy in Middlesex County, where he was hired by a Newton parent to teach his son hockey, remains held without bail. 

Prosecutors Kate MacDougall and Michael Doolin also agreed to a final pretrial conference in the case on May 2. 

The trial will take place either in Salem Superior Court or Lawrence Superior Court. 

The case came to light in February of last year, when the mother of one boy went to police after her son disclosed that Prew had touched him inappropriately while babysitting him. Prew had befriended the boy's mother and had offered to spend time with the boy after the loss of his father. 

After those allegations became public, multiple other boys came forward to disclose that they had also been touched.  

Prew's mother, Louise Martino, 56, of Winthrop, has lost a motion seeking to dismiss a witness intimidation charge against her and is due back in court on March 8. 

Martino and her attorney had argued that the evidence presented to the grand jury for an indictment did not include proof that Martino was actually the sender of a message on Facebook to the mother of the first boy. That message appeared to threaten to disclose personal information about the woman if she pursued the charges against Prew.

Judge Salim Tabit denied the motion on Jan. 28.
