A British graduate on a Swiss skiing holiday was brutally murdered with a metre-long candlestick by a millionaire art dealer’s son, a court heard yesterday. The victim, (inset), 23, a former pupil of Prince Charles’s public school Gordonstoun, had his head caved in before being slashed with glass and choked to death, it was said. His alleged killer (right), 31, who was high on cocaine and ketamine at his parents’ chalet, mistook the victim (right in left picture with his mother) for a green alien in his stupor, it was claimed.
