A 14-year-old Massachusetts high school student charged with killing a teacher has been ordered held without bail.

Philip Chism was ordered held at his arraignment in adult court on a murder charge in Salem. Prosecutors say the teen beat well-liked Danvers High School math teacher Colleen Ritzer to death. Her body was found in the woods behind the school early Wednesday . 

Essex District Attorney Jonathan Blodgett said police started investigating after they learned she had not returned home from work and was not answering her cellphone. Investigators found blood in a school bathroom and soon located the victim. Blodgett did not say how Ritzer died.  (Associated Press)
