Marion Adams - a multimedia teacher and track and field coach at Rio Londa High School in California - died this week in a terrifying bicycle accident, reports The Sacramento Bee.
The 59-year old was riding away from practice on Monday when he looked over his shoulder to bid farewell to a student.
Tragically, Adams therefore failed to see a partially opened metal gate in the school parking lot and could not slow down in time to avoid it.
He was impaled on the structure, rushed to Mercy San Juan Hospital and initially survived two surgeries to treat internal injuries before passing away.
"Marion was the most popular and nicest man on campus; just a great guy," Athletic Director Mike Morris told the newspaper. "It's a huge loss, devastating to our community.”
Hundreds attended a vigil held for Adams on Tuesday night.
Adams, who coached at his alma mater, is survived by wife Kathy, son Joe and daughter Sarah and two grandchildren.
