A former lab manager at Northeastern University has been convicted of staging a hoax explosion at the Boston campus and then lying about what happened to a federal agent.

Jason Duhaime, 46, from San Antonio, Texas, was convicted on three counts Friday by a federal jury. He faces up to five years in prison and a fine of up to $250,000 for each offense.

Two attorneys representing Duhamie withdrew from the case in January, court documents show. A public defender who replaced them could not immediately be reached for comment Saturday.
