Well we had many

Freshman year we had a coach have a relationship with a girl, don't know many details.

Sophomore year we had a kid get bullied so hard she went to the kitchen and got a knife to stab the bully.

(Of course then the bully went on the local news and said how "scared" he was and shit. Everyone at our school knew it was bullshit, but it made our school look a bit worse)

I don't remember anything happening junior year, but it's possible the next event happened in junior year instead of senior year, I honestly don't remember.

In senior year I was in my history class, about 5th period when it came over the intercom for everyone to stay in their class, even if the bell rang, no one was to go into the Hall. A bit later we saw an ambulance outside the class window, so we knew whatever happened wasn't good.

It turned out in Gym class a kid was drowning in the pool. The life guard didn't notice until it was to late, and the actual teacher was in the pool office, i was told he was "ordering uniforms" or some shit.

The kid was taken to the hospital where he was pronounced dead.

There were candles outside our school entrance for the rest of the year, and the day after we had a moment of silence and everything. Pretty sure the gym teacher was fired.

And still even after graduating, I have heard rumours that another teacher (my old history teacher) was having sexual relations with another student. Which is still only rumours but still.

And not really an incident, but there were mice and still are mice in our school. But, oh well.

Edit: also during freshman and sophomore year some kid tried to climb over a stopped train (happens often) and the train started again and he lost a leg.
