LEBANON — The twin sister of the Tannery Lane man charged with arson is facing an additional charge of falsifying physical evidence in connection to her brother’s arson case.

Andrea Kate Gilbert, 27, of 21 Tannery Lane, is charged with two counts of falsifying physical evidence.

She appeared in the 2nd Circuit District Court in Lebanon Tuesday morning for a probable cause hearing on the initial charge. She was also arraigned on the second charged in court Tuesday morning.

Police allege Gilbert erased information on her cellphone to hide from investigators the communications she had with her twin brother — Anthony Boisvert, 27, of 8 Tannery Lane in Lebanon — who police say is the arsonist behind the First Baptist Church fire that occurred “while believing that an investigation is pending or about to be instituted, she destroyed or removed information and/or data contained on her cellphone by sending a remote signal to her cellphone which erased the information and/or data contained on the cellular phone,” the arrest complaint says.

While investigating Boisvert in connection to two arsons in the city on Dec. 28 and Dec. 29, police interviewed Gilbert while searching for Boisvert.

“Andrea told us that Anthony had some mental health issues, but she was not going to tell us what the conversation was that she had with her brother,” Lebanon police Lt. Matthew Isham said during Boisvert’s probable cause hearing in the court Tuesday afternoon. “At that point we seized her phone to obtain a search warrant for it.”

Lebanon District Court Judge Henrietta W. Luneau arraigned Gilbert on the new charge and found probable cause existed in the initial investigation, meaning that the charge is now bound over to the Grafton County Superior Court.

Luneau ordered Gilbert’s bail be set at $15,000 personal recognizance, and $5,000 cash or surety, and she was returned to the Grafton County House of Corrections.

She is also ordered to have no contact with her brother, who is facing arson and assault charges.
