A condemned man wants his upcoming execution delayed on the grounds that his 217 kilogram frame could lead to a 'torturous and lingering death'.
Ohio inmate Ronald Post is scheduled to die in January for the killing of a hotel clerk, Helen Vantz in Elyria, nearly 30 years ago, reports the Associated Press.
However, lawyers have filed papers claiming his weight, vein access, scar tissue and other medical problems would mean executioners would encounter problems and that the execution gurney may not hold him.
"Indeed, given his unique physical and medical condition there is a substantial risk that any attempt to execute him will result in serious physical and psychological pain to him, as well as an execution involving a torturous and lingering death,"the AP reported the filing as indicating.
Ohio inmates are executed with a dose of of pentobarbital, usually injected through the arms. And filings indicate medical personnel have struggled to insert IV's into Mr Post's arms on previous occasions.
The court filing also indicates Mr Post has struggled to lose weight despite his best efforts as knee and back problems have made it difficult to exercise.
The filing also reveals that Mr Port's requests for gastric bypass surgery has been denied and his severe depression means he struggles to control how much he eats.
Post has tried losing weight, but knee and back problems have made it difficult to exercise, according to his court filing. It is also claimed Mr Post "used that prison's exercise bike until it broke under his weight."
A spokesperson for the prisons department has no comment on the appeal.
