A Sarasota County man has pleaded guilty in federal court to two counts of possession of explosives by a convicted felon.

Now, 57-year old Marc Levene faces up to 20 years in prison when he is sentenced in December.

Federal investigators began looking into Levene in 2016 for selling explosives without a license. In February, federal agents and the Sarasota County Sheriff’s Office executed multiple search warrants and seized more than 7,700 pounds of explosive fuses and hundreds of rounds of ammunition.
