i honestly don& #39;t know how to say this.. Sean Matarazzo -- someone i ran with on a Cross Country team for three years in HS -- is the one who shot and killed Walter Wallace Jr. on the streets of Philly as he went through a mental health crisis. Sean has been a white supremacist.

Sean spouted white power beliefs since he was 15 years old. We-i, did not hold him accountable as we should have. Sean wanted to join the military from the age of 16. Sean is a product of the white suburbs. He is not a member of Philly& #39;s community. He must go to jail for life.

White people, this is a reminder to all of us that shit ain& #39;t no joke. Sean wasn& #39;t joking at 15 when he talked about black people being animals. He stayed true to his ideology 10 years later with a badge and a gun. i am sick to my stomach. this is what CRN High School is about.

This is why white people must hold each other accountable early and often in life. We did not have the tools then, but we should have. and after i got those tools i should have been reaching out to people like him. i am sick. white people, we are all sick.
