WATCH: The mother of murdered Hamilton teen says he'd been bullied since the second day of school

The mother of a 14-year-old boy who was stabbed to death outside his high school in Hamilton this week says ``everyone'' failed her son.

Shari-Ann Bracci-Selvey, whose son Devan was killed in front of her on Monday at Sir Winston Churchill Secondary School, held an emotional news conference this afternoon.

She told reporters that Devan's school year had been going ``to hell'' because of bullying and blamed school authorities for not doing enough to prevent his tragic death.

She added that even she could not do enough to save Devan, saying she ``couldn't get to him in time.''

Bracci-Selvey says she hasn't slept since witnessing the attack on her son, and she relives the horror every time she closes her eyes.

Hamilton police say two people, an 18-year-old man and a 14-year-old boy, are charged with first-degree murder in Devan's death.
