The director of security for the Beijing Olympic organizing committee said Wednesday the U.S. Federal Bureau of Investigation and American Embassy were invited to directly participate in the investigation into the stabbing of two family members of the U.S. Olympic volleyball coach last week.

Liu Shaowu said Tang Yongming, 47, was “encountering family difficulties and was extremely depressed” when he attacked and killed Todd Bachman and seriously wounded his wife Barbara at Beijing’s Drum Tower, a popular tourist destination.
“This is an isolated incident,” he said. “The police have already investigated this whole incident very closely already and announced the results…. We don’t think there will be any effect on the Olympic Games themselves.”

Shaowu said recent increases in security–two armored tanks were parked outside the official media center Tuesday–did not indicate an increased threat to Olympic visitors or media.
