Wanted: Healthy Eastern Box Turtle(s)

My 12-year-old son and I just lost (i.e., he died) an eastern box turtle that we found with a serious respiratory infection that he could not overcome (despite 3 injections of antibiotics and more than $300 spent at the vet). We have a nice outdoor virarium for spring/summer time and a newly equipped and heated indoor tank for wintering turtles. (In the past we've hibernated the box turtles we've found locally, but this guy was too malnourished and sick to hibernate.)

My son was particularly attached to this turtle, so I'm looking for a replacement. If any one knows of one or more eastern box turtles available for adoption, I'd really appreciate a heads up.

Many thanks.
