A former Bowdoinham man who downloaded sexually explicit images and videos of children while at his parents’ house in Oakland in 2012 pleaded guilty on Thursday in U.S. District Court in Bangor to a charge of possession of child pornography.

Daniel Lajoie Jr., 46, who now lives in Oakland, faces up to 10 years in federal prison and a fine of up to $250,000 at sentencing. A sentencing date was not immediately available.

Lajoie has remained in federal custody since his arrest on April 24.

Agents from the Department of Homeland Security began investigating Lajoie after they suspected he was sharing sexually explicit videos of children online, according to an affidavit filed with the court by a Homeland agent Monday.

Authorities first executed a search warrant on Aug. 22, 2012, at the home of Lajoie’s parents in Oakland, where his father told them that the son frequently visited and brought his laptop computer with him. Agents on the same day went to Lajoie’s home in Randolph, Loren Thresher of Homeland Securities Investigations said in the affidavit.

During questioning, Lajoie admitted that he downloaded child pornography on his laptop while at his parents’ house and allowed agents to examine his computer, revealing 50 images and 110 videos of child pornography, Thresher said.
