The Beijing Olympics got off to a rough start as a crazed attacker assailed two American tourists and a Chinese tour guide with a knife this morning, killing a man and wounding two women. The murder victim was a relative of the U.S. men's volleyball coach. The assailant committed suicide after the attack, according to authorities, throwing himself off the 45-meter Drum Tower. U.S. softball player Laura Berg and USOC spokesman respond to the tragedy after the jump.
