A Kennebec County grand jury on Friday handed down indictments totaling nearly a dozen charges against a New Hampshire couple accused of sexually assaulting young children while living in Oakland.

Stephen R. Smith, 37, and Sarah B. Conway, 27, both of Canaan, New Hampshire, are charged with a variety of sex crimes against children and endangering the welfare of a child in connection with incidents that took place between Dec. 1, 2014, and March 31, 2015, in Oakland.

The couple was initially arrested in November. Smith continues to be held at the Kennebec County jail in lieu of $50,000 cash bail. Conway was released on bail on Dec. 9.

The grand jury indictments against Smith include sexual misconduct with a child, two counts of visual sexual aggression against a child and three counts of unlawful sexual contact.

The grand jury indicted Conway on two counts each of visual sexual aggression against a child and endangering the welfare of a child.

An indictment is not a determination of guilt, but it indicates that there is enough evidence to proceed with formal charges and a trial.

The victims are younger than 12 and 16, according to indictment documents.

Arrest affidavits filed in the court indicate that Conway went to the police in Canaan, New Hampshire, Sept. 16 and spoke to Sgt. Ryan Porter, saying that Smith was her former partner and that they used to watch child pornography together when they had apartments in Oakland, Maine, from December 2014 to March 2015. According to Porter, Smith told her he had sexually abused his own children and talked her into sexually abusing her children.

According to the affidavit by Oakland Police Detective Capt. Rick Stubbert, Porter told him that “Sarah thought she did this because she liked Stephen so much and she didn’t know how to say no.”

Conway told police the sexual contact occurred in Oakland.

After Conway talked to the New Hampshire officer, Porter said Smith agreed to go to the Canaan Police Department to be interviewed. There, according to Porter, Smith confirmed what Conway had said and indicated he touched the genitals of the two children and had them touch his and that sometimes it occurred in the bath and in the bed with Conway.
