Kardashian's Twitter pleas for Davis

Los Angeles - Kim Kardashian tried to save a death row prisoner.

The newly married reality TV star urged her Twitter followers to support convict Troy Davis, who died by lethal injection in the state of Georgia on Wednesday for the killing of police officer in 1989.

Before the execution, Kim tweeted: "I want to vent about the execution of Troy Davis! He is getting the death penalty tonight but I believe he is innocent!!! (sic)

"All he wants is a polygraph test 2 prove he's innocent & the judicial system can't give that to him? (sic)

"Everyone google Troy Davis & read his story! NO ONE should die by lethal injection when there is this much doubt! (sic)"

Davis claimed he was the victim of mistaken identity but his pleas for clemency to the Georgia State Board of Pardons and Paroles were rejected.

Unsuccessful

Davis died by lethal injection on Wednesday for the shooting of off-duty policeman Mark MacPhail, who was aiding a homeless man in a Burger King parking lot at the time of his death.

Many other stars have also leant their support to Davis's campaign, including Lindsay Lohan, John Legend, Samantha Ronson and Mia Farrow.

P. Diddy even gave out a number for United States Attorney General Eric Holder to his Twitter followers, adding: "Urge him to intercede on Troy Davis - retweet to the world and call right now! (sic)"

He later tweeted: "May God have Mercy on their Souls". "May God Bless your Souls" - Troy Davis RIP."
