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.

This is ritual murder at its most obvious. A central, ancient location, full of power and energy.

About the Drum Tower.

The Drum Tower is an interesting building.  It is paired with the Bell Tower, in an aligned pattern in northern Beijing.

The drum and bell are favorite symbols for ritual sacrifices.
In 1924, the name of the building was changed to the Tower of Realizing Shamefulness (Mingchilou) and objects related to the Eight-Power Allied Forces’ invasion of Beijing and later the May 30th Massacre of 1925 were put on display. (Source)
