 Investigators say the 17-year-old may have given Javarius Heard a cup of soap, which he threw in the face of a female corrections officer. She was beaten and suffered minor injuries. He then walked away and was cleared outside by 49-year-old Corey Prue, who tried to restrain Heard. Prue was thrown to the ground. He hit his head on a sharp object. Prue was rushed to the scene, but later died.
