A twisted teen who savagely raped and murdered his pretty high school teacher has been convicted — thanks to jurors who decided his insanity defense was nuts!

Philip Chism’s butchering of 24-year-old Colleen Ritzer in a girl’s bathroom at Massachusetts’ Danvers High was an “excruciatingly horrifying” premeditated act according to District Attorney Jonathan Blodgett.

But Chism tried to weasel out of the charges, claiming he killed Colleen because he was in the middle of a psychotic breakdown!

“It just wasn’t proven,” said juror Maureen Strileckis, 51, who didn’t buy Chism’s insanity defense.

At the trial, prosecutors chillingly told how then-14-year-old Chism arrived at school with all the gear he needed to commit the horrible Oct. 22, 2013 crime.

Chism, who stands 6-foot-2, brought a backpack loaded with a ski mask to cover his face, gloves to prevent fingerprints, and a box cutter to slash the 24-year-old beauty.

“He had a goal – a terrible, terrible purpose,” declared Assistant District Attorney Kate MacDougall.

Security cameras caught the fiend following the math teacher into the restroom where he raped her and slashed her 16 times. Then, he stuffed her into a recycling container, dragged it to nearby woods, and violated her again with a tree branch.

Video footage showed him returning to school in jeans drenched with her blood.

Jurors, convinced Chism killed Colleen with deliberate premeditation, returned a guilty verdict within two days.

“I don’t have any regrets about the outcome, so that’s one good thing,” said juror Maureen.

Chism faces a life sentence at a Jan. 29 hearing. He awaits another trial for attacking a woman in a restroom at the facility where he was being held.
