When I was a bursar at an lea school, one of the kids killed one of the others out of school. The teachers were the best you could hope for and counselled the pupils and got them all together offering advice and support, and the kids themselves are often the best support network for each other, get them to support each other. Only my own opinion, once the professional councellors arrived on scene after a day or so, problems arose, kids became traumatized and shocked by the way they were counselled!! My advice is to keep the Councellors away from your boy and use the network of family, friends and the school group for support.
