Attorneys from Pennsylvania and Kansas City were in Miami this week revisiting evidence in a 20-year-old murder case.

Amy Donnella, a Pennsylvania defense attorney, is hoping to find evidence for probable cause to overturn the death sentence of Shannon Wayne Agofsky.

Agofsky is sitting on death row in Texas for the 2001 murder of Luther Plant, a fellow inmate.

Agofsky was serving a life sentence in Beaumont, Texas, at the time of the fatal beating and stomping of Plant.

He was originally convicted in the 1989 death of Noel banker Dan Short.

Prosecutors contended the Agofsky and his brother Joseph Agofsky abducted Short from his northwest Arkansas home early Oct. 6, 1989, took him to the State Bank of Noel, Mo., and forced him to open the vault so they could rob it of $71,000.

Short was then driven into northeast Oklahoma, tied to a weighted chair and dumped alive off the Cowskin Bridge near Grove. His body was found five days later.

The trial was moved to Stillwater from Ottawa and Delaware counties because Fullerton ruled an impartial jury could not be seated in northeastern Oklahoma.

The brotherís were sentenced to life in federal prison in 1992 for robbing their hometown bank.

"The previous conviction of murder was the basis for imposing the death penalty on the federal charges for murdering the prison inmate," said District Attorney Eddie Wyant, who tried the murder of Dan Short in Stillwater.

According to Wyant the defense is now claiming Agofsky had ineffective council during the Plant murder trial.
