Does this man look like a serial killer?

On the left is Colonel Russel Williams, commander of Canada's largest air force base and a rising star in the armed forces.

And it has all come to a shocking end. Canadian police working on a missing persons case believe he is responsible for two murders and two very serious and nasty sexual assaults. They suspect there may be others, perhaps going back years.

One of the murdered women was a subordinate, a corporal on the base he commanded.

You will be relieved to hear he has been relieved of his command.

And we are all left to wonder why?
