ALFRED — An alleged bomb maker whose activities were uncovered when he blew part of his finger off is due to stand trial next month in federal court.

Robert Infante dialed 911 last June from his Alfred home to say he’d been injured by a propane tank explosion. He ended up driving himself to the hospital, but firefighters still went to Infante’s home. There, they found about 12 pipe bombs and a marijuana-growing operation.

More pipe bombs were found in the trunk of his car at Southern Maine Medical Center in Biddeford.

The Journal Tribune newspaper says he’s due to stand trial June 6 on charges of possession of a destructive device and various drug and firearms offenses. Infante was convicted of similar offenses in Vermont in 1988.
