On March 19, 1982, just before the start of class, Clarence A. Piggott, a high school psychology teacher was getting ready for his daily routine when a disturbed student who came to school to resolve a problem he had with a different teacher. In the student’s paranoid schizophrenic state of mind the best solution was to shoot Piggott in the heart with one bullet from a 22-caliber revolver. Lizotte then concealed the gun in the green camouflage jacket he always wore and m
ade his way through the very crowded hallways of Valley High School and onto the residential streets of Las Vegas. Piggott had once warned students to lay off the student, because if he ever snapped, it would be ugly. It seems that people knew that there was a risk, but other than Piggott few reached out to help. Piggott died without saying a word to anyone, only holding the hand of a co-worker.

I loved Mr. Piggott. He used to call me “Cisco” because I was skinny…lol
I graduated VALLEY HIGH SCHOOL in 1978. I went back several years later & apologized to him that it took me so long to come back to catch up. He looked at me with that same playful, penetrating way that he used to..and asked me “Why? You are supposed to look forward now…not behind” I never forgot that, so today as a teacher myself, I say the same thing to my own returning students.
I have no clue why the photo of Spring Valley HS is on this page…it is an error. Please have honor and get the correct high school listed.
The picture of the school is incorrect. The school where this occurred is Valley High School, Las Vegas, NV. The school pictured did not open until decades later.
I knew him… he was my psychology teacher at Valley night school and I had just left there when Valley night school switched to Las Vegas High School night school that was named Urban Evening High and parents objected to “Urban” so students were asked to give name suggestions and we came up with Sunset Evening High. After that I heard he was shot and died…I couldn’t believe it.
I knew him well. His wife worked at Las Vegas High where I was an Industrial Arts Teacher. They were both very good people. I also spent a lot of time at both Valley and Sunset. Beyond shocking
