Spot has been found! You can take down the missing head fliers off your mail boxes.
After getting the run around from 1.800.Go.Fedex for a week, with a half a dozen unreturned calls I started looking for people who work at the facility.
On Friday the 21st I ran a Nexus search on Fedex Ground Sacramento. It came up with an obscure news report from Kansas City of all places in which a Senior Terminal Manager for the ground location in Sacrameto was quoted and named. Bingo... right. Not really Fedex is big on internal security for good reason. Searching out employees is frowned on.
I finally found an obscure listing on a job bulletin board with the terminal managers e-mail contact address. (they need an admin clerk in Sacramento BTW, $12. p/h and bennies)
I contacted him via e-mail last Friday asking for his help. Today I received a reply... Spot is alive and well, living at the "overstock station" in Ohio. He will be on his way back tomarrow.
Thanks for all who looked, especially Freddie who went out on a limb to help.
