Matt Micciche, the head of school, said the campus community was “shocked and saddened by the news of this horrific attack.”
“Our school — and the Religious Society of Friends — has a long history of commitment to diversity,
racial equality, social justice and nonviolence,” Mr. Micciche said in a statement.
“He said, ‘Listen, I wrote this all down, it’s in my laptop,’” the law enforcement official said.
“He was known in the community as not to be someone who started a fight, but if you started it, he finished it,” said one of his cousins.
“He probably gave out about two or three thousand jobs to people in the community,” said one of his cousins.
At the arraignment, Joan Illuzzi, the prosecutor, said that Mr. Jackson was particularly offended by black men who were with white women.
