i saw similar, working in the UK arm of a US mid size. Embarking on a huge global project, a us morning team conf call led by the instigator of said project who had been moved into a special position 8 months earlier to have more control of delivering that project, my colleague leans over to me and tells me this guy is out the door. Sure enough by UK after lunch he had gone. No good bye, nothing, just gone. Took another 2 years to deliver that project, especially as we where hindered by decision choices the ousted man had made which intern where made to satisfy the boards desire to save money.
