Alec Baldwin has never been scared to speak his mind, and the highly acclaimed actor is determined to have his disgust over the execution of Troy Davis heard loud and clear, RadarOnline.com is reporting.

The 30 Rock star took to Twitter on Wednesday night within minutes of Davis' execution, which occurred at 11.08 p.m. EST by lethal injection, despite a last ditch plea for clemency.

"The anti-justice haters won tonight," Baldwin tweeted shortly after Davis took his last breath.

Troy Davis’ sister Kimberly, has spoken of her time with her brother just prior to his execution Wednesday night by Georgia authorities, sharing that: "Our last moments were joyous.”

“My brother was giving us charge as to what he wanted us to do, telling us to hold our heads up, telling my nephew to continue to be all that he could be,” she continued.

“My niece was showing him her ballet shoes and telling him to stand on his tippy toes like a ballerina," Kimberly told ABC News from her Savannah, Ga., home.

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.

Troy Davis, the man who was scheduled to be executed at 7 p.m. on Wednesday has filed an eleventh-hour plea asking the U.S. Supreme Court to stop Georgia authorities from carrying out the death penalty, a sentence he was given when he was convicted of murdering an off-duty police officer.

Georgia prison officials were still waiting, at the time of posting, for the high court’s decision about the fate of the 42-year-old who was sentenced to death in 1991. 

Despite an outpouring of support to have the death penalty judgment repealed, the Georgia Board of Pardons and Paroles denied Davis’ plea for clemency and the Georgia State Supreme court denied his plea as well.

Followers of Kim Kardashian on Twitter are used to her tweeting about her latest fashion line, reality show or inane pop culture obsession, but the reality star's updates took on a serious tone on Wednesday as she passionately pledged her support of death row convict Troy Davis.

"There is #TooMuchDoubt to kill Troy Davis tonight," the newlywed wrote in her latest tweet, advising her fans to visit the website GlobalGrind.com for more information on his case.

As RadarOnline.com previously reported, the last desperate plea for clemency made on behalf of Davis was turned down on Tuesday, despite having received an outpouring of support from those who believe that he was wrongly accused of killing a police officer in 1989.

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.

With his scheduled execution only hours away, the Georgia Board of Pardons and Paroles has denied a last-minute plea for clemency from Troy Davis, who claims he is innocent in the August 1989 death of Savannah police officer Mark MacPhail.

The 5-person board said in a statement Tuesday they "have not taken their responsibility lightly and certainly understand the emotions attached to a death penalty case."

Following the decision, the late lawman's son, Mark MacPhail Jr., said that "justice was finally served for my father; the truth was finally heard."

The last desperate plea for clemency made on behalf of death row inmate Troy Davis was turned down on Tuesday, RadarOnline.com has learned, despite having received an outpouring of support from those who believe that he was wrongly accused of killing a police officer in 1989.

However, the convicted killer's supporters have still not given up hope as Davis' sister spearheads a campaign to save her brother.  Kim Davis launched an online petition 11 days ago at Change.org to appeal to the Georgia Board of Pardons and Paroles, and currently has 250,000 signatures supporting her sibling.

"She is not going to stop trying, she said she is going to keep pushing for this up until the very moment that it might happen," Jonathan Perri, Senior Organizer of the Criminal Justice division of Change.org told RadarOnline.com in an exclusive interview.

A man set to be executed on Wednesday is going for a last minute plea for clemency in order to avoid the death penalty and multiple witnesses have come forward to support his claim of innocence.  

Troy Anthony Davis was convicted of murdering an off-duty police officer in 1989, but his legal team is arguing that there is “abundant evidence” that another man committed the murder and say that they have “sworn statements from three jurors who sentenced Davis to death at his 1991 trial, but who now express doubt with their verdicts and are asking that Davis be spared the death penalty,” according to the Atlanta Journal and Constitution.

Davis’ attorneys have filed the clemency petition with the Georgia Board of Pardons and Paroles, noting that seven of the prosecution’s nine witness have either recanted or backed off their testimony.  More witnesses have come forward to say in sworn statements that Sylvester “Redd” Coles told them he was the one who pulled the trigger in the murder of Mark Allen MacPhail.  Coles was at the scene of the crime with Davis.
