The reverend and former high school dean who authorities say shot a 17-year-old male student over a marijuana dispute may face more charges after a police search of his Roxbury home yielded drugs and guns.

Inside Shaun Harrison’s 18 Pompeii St. home were two handguns, a rifle, a shotgun, multiple calibers of ammunition, “trafficking weight of cocaine and a large amount of marijuana.”  

Harrison, 55, was fired from Boston English High School last week after cops said he shot a teen in the head Tuesday on Magazine Street. He was arrested on Wednesday and arraigned on Thursday.

Prosecutors alleged Harrison ran a marijuana ring and used the victim to sell the drugs.

Boston detectives continue to investigate but described seeing a large gang mural during the search of Harrison’s apartment.
