BANGOR, Maine — In a barely audible voice, a former RSU 67 educational technician pleaded not guilty Thursday at the Penobscot Judicial Center to charges related to her alleged sexual abuse of a 15-year-old male student this summer.

Tammy L. Larlee, 45, of Lincoln was indicted last month by a Penobscot County grand jury on four counts of gross sexual assault and four counts of sexual abuse of a minor, all Class C crimes.

Larlee is next scheduled to appear in court on Nov. 5.

The longtime ed tech appeared alone before Superior Court Justice William Anderson. The judge set personal recognizance bail. Conditions include no contact with the victim and minors under the age of 17. She also may not be on any school property in the district, which includes Lincoln, Chester and Mattawamkeag, without permission from district officials.

Anderson determined that Larlee qualified for a court-appointed attorney because of her limited income. The justice appointed Nolan Tanous of Millinocket to represent her.

Larlee and the boy had sexual intercourse twice in June and twice in July, Alice Clifford, the Penobscot County assistant district attorney who is prosecuting the case, said last month.

Clifford said that because Larlee essentially had a teacher-student relationship with the victim, she was charged with a felony.

Lincoln police discovered the alleged sexual assaults and abuse while investigating a separate incident, the prosecutor said Thursday. Clifford said it was unclear to her what Lincoln police were investigating that led them to Larlee.

Larlee worked for the district from 1999 until last month, when she resigned, Ray Freve, superintendent for RSU 67, said last month. Freve attended Thursday’s hearing.

Her last assignment was working at Mattanawcook Academy in Lincoln, he said last month.

Clifford said last month that Larlee met the victim while working at the school.

Ferve said after Larlee’s arraignment Thursday that he attended to make sure her bail conditions included that she not be allowed on school property.

He said that he had met with teachers, staff and relatives of the victim before school began earlier this month to make sure all “are looking out for the child.”

Ferve has declined to answer questions about how the child is doing since information about the charges against Larlee became public when she was indicted Aug. 28.

If convicted, Larlee faces up to five years in prison and a fine of up to $5,000.
