3 Accused Of Lying In Fitchburg Missing Boy Case

Three people are accused of lying to police investigating the disappearance of Jeremiah Oliver, a 5-year-old Fitchburg boy reported missing last fall and feared dead.

Jeremiah's mother, Elsa Oliver, and her boyfriend, Alberto Sierra Jr., are in custody after pleading not guilty last year to child endangerment and abuse of Jeremiah's siblings. They haven't said where Jeremiah is. He was last seen by other relatives in September.

Sierra's 21-year-old brother Christian Sierra, and two friends of Oliver, 24-year-old Ashley Cormier and 23-year-old Casey Thibault, pleaded not guilty Monday in Fitchburg District Court.

The Fitchburg Sentinel & Enterprise reports Christian Sierra posted $2,000 cash bail. Bail for Cormier and Thibault was set at $2,500.

Cormier's father told WFXT-TV his daughter doesn't know anything about Jeremiah's disappearance.

The state's child welfare agency has been criticized for losing track of Jeremiah.
