Police have announced three additional arrests in the case of missing Fitchburg boy Jeremiah Oliver, according to the Sentinel and Enterprise newspaper.
Cailey Thibeault, 23, Christian Sierra, 21 and Ashley M. Cormier, 24, all of Fitchburg, were arrested and charged with intimidation of a witness.
Investigators believe Christian Sierra, 21, of Fitchburg lied to the grand jury about details related to the case, which may have slowed down or misled the investigation, according to court documents at Fitchburg District Court, where the arraignment was held.
Also arraigned were Ashley Cormier, 24, of Fitchburg and Casey Thibault, 23, of Fitchburg, both of whom are identified as friends of Jeremiah Oliver's mother and her boyfriend. They are each being held on $2,500 cash bail.
Sierra is the brother of Jeremiah Oliver's mother's boyfriend, according to the report. Jeremiah's mother, 28-year-old Elsa Oliver, and her boyfriend, 23-year-old Alberto L. Sierra Jr., were also arrested on child abuse charges in connection with the case last year.
The five year old boy has been missing since September.
