HALIFAX – The stepfather of two Nova Scotia children reported missing more than eight months ago has been charged with sexual assault, assault and forcible confinement involving an adult victim, RCMP confirmed Thursday. No other details were released and Martell was not immediately available for comment. The documents, filed to support applications for search warrants as part of the police investigation into the missing children, include other unproven allegations and statements by police. The documents also say that on May 2 and May 4, Martell told police the couple had recently been fighting about money, but no other details were provided. Martell has made many public statements insisting he played no role in the children’s disappearance, which has attracted international attention.
