It has been reported by NBC Washington that Bennett was involved in the May 1999 NATO bombing of the Chinese embassy bombing in Belgrade during NATO involvement in Yugoslavia. Three Chinese citizens were killed in the attack. This accidental bombing was later blamed on an outdated map that showed the embassy at its prior location. The CIA later took responsibility for the error, firing one officer and reprimanding 20 more. It is unclear at this time the level of Bennett’s involvement and whether or not it might be linked to the deadly attack that took his life.
The Sheriff's Office continues to investigate the murder of William Bennett and the assault on his wife, Cynthia Bennett. They are receiving assistance from several organizations in the investigation.
