• More arrests made in case of missing Fitchburg boy


    FITCHBURG, Mass. (MyFoxBoston.com) -- Three more people were arraigned Monday in relation to the disappearance of missing 5-year-old Fitchburg boy Jeremiah Oliver.

    Christian Sierra, 21, Cailey Thibault, 23,  and Ashley M. Cormier, 24, all of Fitchburg, are charged under the intimidation of a witness statute.

    Sierra and Thibault were arrested Friday night and held on $25,000 bail.

    Cormier was arrested Monday.

    All three suspects are accused of lying to a grand jury investigating the 5-year-old's disappearance.

    Christian Sierra is the brother of Alberto Sierra, the boyfriend of Jeremiah Oliver's mother. Investigators claim he denied speaking with his brother, but phone records showed numerous calls made around the time he was being interviewed by investigators.

    Christian's girlfriend, Cailey Thibault, is also accused of lying about phone calls and a meeting she had with Alberto and Jeremiah's mother, Elsa Oliver. Court documents allege some of the calls were made on a second phone that she never told investigators about.

    Court documents also allege Thibault threatened Jeremiah's mother with violence in the days after his disappearance became public. Investigators allege she threatened to physically harm Elsa Oliver, a woman who came to court with two black eyes.

    Cormier, who is close with Oliver, was reportedly by her side when news of Jeremiah's disappearance first went public. She is also accused of lying about phone conversations.

    Sierra was held on $2,000 bail Monday. Thibault and Cormier were each held on $2,500 bail. A judge continued their case to April 15.

    Alberto Sierra is currently in jail awaiting trial on two counts of assault and battery with a dangerous weapon, and two counts of assault and battery on a child causing bodily injury.

    Elsa Oliver, Jeremiah's mother, was also arrested in connection with her son's disappearance. She is facing charges of reckless endangerment of a child and accessory after the fact.

    Jeremiah Oliver was reported missing in early December, though he hadn't been seen by relatives since September. Authorities fear he may be dead.
