Currently locked in a prison cell in Tehran after being sentenced to death, Iranian-American Amir Hekmati is an unfortunate victim of the increased tensions between Iran and the U.S., a Middle Eastern expert at Amnesty International exclusively told RadarOnline.com.

"His treatment falls into a very known pattern of people who are trotted out and accused of espionage," Elise Auerbach, Iran Country Specialist of Amnesty International USA told RadarOnline.com in an exclusive interview.

However, it is the severity of the sentence that is unusual and is shocking to the human rights group.

Despite a last ditch plea for clemency and a huge rally to grant a stay of execution, Troy Davis was put to death at 11:08 p.m. Eastern time on Wednesday September 21, RadarOnline.com can report.

The convicted murderer, who maintained his innocence to the end, was executed by lethal injection, Kristen Stancil, a spokeswoman for the prison where Davis died, confirmed.

As RadarOnline.com previously reported, Davis was sentenced to death for the 1989 murder of Savannah police officer Mark MacPhail, who was gunned down while rushing to the aid of a homeless man in a Burger King parking lot.

The clock is ticking on what could be Troy Davis' final day alive, and RadarOnline.com has an exclusive insight into his life on death row.

Despite an outpouring of support to have the death penalty judgement repealed, the convicted killer, who maintains his innocence, is scheduled to be executed at 7 p.m. EST on Wednesday.

"He’s got no possessions right now, they took away his address book - everything. They even took away part of his pen so that it can’t cause him harm, so now he writes with just the barrel," a friend of Davis’ told RadarOnline.com in an exclusive interview.
