Very sad news indeed, to be taken at such a young age and with his whole life before him, seems he was a good lad by all accounts, who was doing good for others. RIP young man sincere condolences to his family
I taught him, briefly several years ago. It is rare that individual pupils stay in your memory. He did, as did his class, but he stood out for his intelligence and personality. A real, genuine pleasure to teach and a sad loss.
His family must be in pieces, my condolences to them. They can be so proud of Sam.
