FOREST HILL High School principal Edward Legg, who was almost killed in a hijacking a month ago, died of a suspected heart attack on Wednesday as he was identifying his alleged assailants at a parade. Gauteng police spokesman Inspector Mark Reynolds confirmed Legg’s death. He said a post mortem will be held to determine the exact cause of death and depending on the outcome, the charges against the three accused could be changed to murder. The three hijacking suspects were arrested shortly after the attack, in which Legg was shot twice. They have made several appearances at the Johannesburg Regional Court and have been charged with aggravated robbery, attempted murder and the illegal possession of firearms and ammunition. Legg and his daughter were ambushed at their home after returning from Forest Hill High school, where he had given evening mathematics lessons.
