The victim has been identified as the Reverend Theodore Brown, a 51-year-old family relations specialist for the Springfield school department.
District Attorney William Bennett says Brown got into an argument with the student, identified as Cory Ramos, in a science classroom at Springfield High School.
Bennett says Ramos pulled a knife and stabbed Brown several times in the chest and stomach. The victim was later pronounced dead at Baystate Medical Center.
Bennett says the suspect was arrested about a half-mile from the school, and faces a murder charge. The knife was recovered in the woods behind the school.
Bennett and Springfield Mayor Michael Albano stressed that the attack was not planned, and was an isolated incident involving only the student and victim.
School Superintendent Joseph Burke says Brown was "extremely dedicated" and devoted his life to working with young people. Burke says Brown "died in the line of duty."
