A pair of mentors for students helped prevent a stabbing that happened at a Massachusetts school from becoming much worse.John Williams and Rakim Turner are mentors to Brockton students through the "Get You to the Gate" program who relish the work that they do."It makes you feel like what you're doing on a daily basis is worth it," Williams said."As long as someone is listening, then we can help change minds and keep kids on the right path," Turner said.But their mentoring roles took a frightening turn on Thursday, when a 16-year-old student stabbed a 17-year-old student at the Huntington Therapeutic Day School."He was already in the stabbing motion, so I knew that the other young person was injured already," Williams said. "I just didn't know how bad, and I didn't want it to get worse." Williams and Turner were monitoring students from a different school that is located in the same building as the Huntington Therapeutic Day School when they stepped in to stop the stabbing."By the time I got there, that's when I realized there was a weapon involved, and I needed to literally stop and only take a second to think what happens next," Turner said. The mentors said they got the knife away and held the attacking student down while others tended to the victim. "I feel blessed to have been able to have the capacity to deal with that situation," Williams said.Williams said the stabbing at the Huntington Therapeutic Day School is another example of why all schools should take a closer look at mental health and school safety. "We have to look at our safety protocols in our schools. We have to look at accountability of each one of our students at all times," he said.The 17-year-old student who was stabbed was taken to an area hospital with non-life-threatening injuries.The 16-year-old suspect was arrested at the school and taken to a local hospital to be evaluated. Brockton police later charged that student with assault and battery with a dangerous weapon, attempted murder and carrying a dangerous weapon on school grounds.School officials said there are metal detectors at the facility, so it's unclear how the knife made it through. Brockton Public Schools Superintendent Michael Thomas and Brockton Mayor Robert Sullivan said the sensitivity of metal detectors across the school district is being checked.
