A 16-year-old Massachusetts teenager was found guilty Tuesday of murdering and raping his math teacher at Danvers High School in 2013.
Philip Chism´s attorneys argued the then 14-year-old was suffering from a psychotic disorder. The jury, however, rejected this argument. 24-year-old teacher Colleen Ritzer had been raped twice and her throat had been slit.
A surveillance video from the school shows Ritzer walking into the bathroom, then Chism following her. The teenager was tried as an adult. He faces life in prison on the first-degree murder charge.
