BEIJING, China (CNN) -- A Chinese attacker stabbed to death the father-in-law of a U.S. Olympic coach and seriously wounded the American's wife and a Chinese tour guide before killing himself, the International Olympic Committee said Saturday.
Todd and Barbara Bachman of Lakeville, Minnesota were attacked at the Drum Tower, an ancient monument in downtown Beijing, the IOC and Chinese authorities said.
Barbara Bachman's injuries are "serious and life-threatening," an IOC statement said. The tour guide's condition was not immediately clear.
Todd Bachman was the father-in-law of U.S. Olympic men's indoor volleyball head coach Hugh McCutcheon. McCutcheon's wife, 2004 U.S. Olympic women's indoor volleyball player Elisabeth Bachman McCutcheon, was with her parents when they were attacked, but she was not hurt, the IOC said.
The Bachmans were not wearing apparel that identified them as relatives of members of the U.S. delegation at the time of the attack, the IOC said.
The attack happened around noon at the Drum Tower, a popular tourist site, China's official news agency Xinhua reported.
The assailant, a 47-year-old man from Hangzhou in eastern China, jumped to his death from the tower after the attack, authorities said.
