Harrison arrived at English High in Boston in January 2015, just two months before his arrest and after stints at other city public schools over about five years. He had been a community organizer and youth minister in Boston for decades. When he was hired at English High in January 2015, he beat out about 50 other applicants. Prosecutors said Harrison bragged to students about owning guns and told them he was connected to the Latin Kings gang and had killed someone before. Investigators found guns, ammunition, marijuana and a mural of the Latin Kings in a search of his apartment and storage unit.
Harrison was convicted of shooting Luis Rodriguez. The jury deliberated for about a day before convicting Harrison. They found him guilty of armed assault with intent to murder and other gun- and drug-related charges.
“It was only by sheer luck that the victim survived this attempted execution to identify Harrison for what he is — a violent predator and a fraud,” said Suffolk District Attorney Daniel F. Conley after his conviction.
