A Boston minister who also worked at a city high school before he was charged with trying to a kill a 17-year-old student is now facing drug and gun charges.

Authorities on Monday charged the Rev. Shaun Harrison Jr. with cocaine, marijuana and gun offenses based on a search warrant executed at his home following the shooting last week. He faces a March 17 arraignment.

Authorities say the 55-year-old Harrison was leading a "double life," as a youth minister and anti-violence activist, even as he was allegedly involved in the drug trade.

Harrison is being held on $250,000 bail. Prosecutors say he shot a 17-year-old boy he had enlisted to sell pot for him following a dispute.

After his arrest, Harrison was fired from his job at English High School.
