(NECN) - Three people have been arrested in connection to the disappearance of a Fitchburg, Mass. boy.
Jeremiah Oliver was last seen in September and is feared dead. 21-year-old Christian Sierra, 23-year-old Cailey Thibault and 24-year-old Ashley Cormier were arraigned Monday.
The Worcester County District Attorney is accusing them of interfering with the criminal investigation into the case of the missing boy.
All three have been charged under the intimidation of a witness statute.
Jeremiah's mother, Elsa Oliver, and her boyfriend, Alberto Luis Sierra, have previously been charged in the case and remain in jail.
