death row inmate too fat for execution?

Ronald Post set date for execution, for murdering Helen Hatz in 1983, was for set for January 16th next year but after some "issues" that might not happened as planned. His lawyers are trying to say that he is too fat, weighing at 480 pounds and 6'3, to be executed for his crimes. They are arguing that it would be too hard for them to find the proper vein to do the process. There have been instances in the past when this was an problem for other overweight prisoners. Post has tried to lose weight in the past but claims it is too hard to do in prison. The victim’s son is outraged by this defense saying it is nothing more than an excuse. His weight might really get him out of this execution.
