Is Zombie Trustee Eleiso Medina still "working" at UHW?

Unless I have the wrong email address I think the bounced email message below shows Zombie Trustee Eleiso Medina is no where to be found. It appears the email address scheme used at UHW -- first initial followed by last name followed by seiu-uhw.org when applied to Zombie Trustee Medina -- is routinely kicked back. One Zombie trustee down, one to go!

Emphasis added but you get the idea.
