A Massachusetts jury on Tuesday convicted a teenager of raping and murdering his high school math teacher when he was 14.
Philip Chism followed his ninth-grade algebra teacher, Colleen Ritzer, into a school bathroom, strangled her, stabbed her at least 16 times and raped her.
Chism, now 16, was tried as an adult. He was convicted of raping Ritzer inside the bathroom but was acquitted of a second rape, committed with a tree branch in woods near the school where Chism put her body. He was also convicted of first-degree murder, as well as armed robbery for stealing Ritzer's credit cards and her underwear.
Chism stared straight ahead and did not have any visible reaction...
