State authorities say they have been in touch with 3 of the 4 pardoned killers The attorney general says he'll ask a judge to declare the pardons "null and void" One of those pardoned, Anthony McCray, thanks governor for his decision The outgoing governor last week pardoned him and dozens of others Jackson, Mississippi (CNN) -- One of four convicted murderers whose whereabouts had been unknown since they were controversially pardoned last week by Mississippi's governor insisted Friday that he hasn't been on the run, saying he is a changed man who deserved to be freed. He criticized the outrage over outgoing Mississippi Gov. Haley Barbour's decision to grant clemency to him, along with nearly 200 other convicted criminals, in a final act before leaving office. I didn't do this. God did this," McCray said from a covered porch. God touched Haley Barbour's heart. The office of Mississippi's attorney general said late Friday afternoon that authorities have been in touch with three of the four convicted murderers -- McCray, David Gatlin and Charles Hooker -- who were pardoned and released Sunday. Nathan Kern, an armed robber who is also required to check in with authorities, also has been located. But authorities are still looking for one convicted murderer, Joseph Ozment, the office said. McCray was sentenced to life in prison after pleading guilty to the 2001 murder of his wife, Jennifer McCray. Even with the plea, he insisted Friday that her death was an accident and said the shot was fired inadvertently during "tussling" over a gun. "I didn't know she was shot," McCray said of his initial reaction. I said, 'Somebody, call the police.' (Later) I went and turned myself in. ... This is somebody I loved and had children with. He noted that there were many witnesses, as the woman was shot from behind in a public cafe. And the victim's younger brother, Ronald Bonds, said Barbour should be "ashamed of himself" for pardoning Anthony McCray. McCray said he had his own room at the mansion, spending three years there after serving in prison without any disciplinary problems. During his time in Jackson, he said, he did odd jobs like housekeeping, washing cars and cooking and conversed regularly with Barbour. He added that it was understood that trusties had a much higher chance of getting pardons than those in the general prison population, though he insisted that the two never talked about clemency. "He treated us like we were his children," McCray said. McCray said Friday that he did not know the whereabouts of any of the men, whom he described as "nice guys." Authorities contacted him at his relative's house about 7 p.m. "Everybody deserves a second chance in life," McCray said, expressing thanks for being able to reunite with his son and daughter while acknowledging that it is a "great possibility" he might be ordered to return to prison. The four convicted murderers and Kern, the armed robber, are required to contact prison officials on a daily basis while their fate is adjudicated. The attorney general's office said 203 of those were "full pardons," meaning the convict's record is effectively wiped clean. Hood said Friday in a statement that "a large number of staff" is examining these pardons. "Our preliminary investigation indicates that the majority of these purported pardons did not have sufficient publication and therefore we will introduce our evidence (in court on January 23) and ask the court to hold these purported pardons null and void," the attorney general said. Barbour said Wednesday that some people misunderstand the clemency process, noting that approximately 90 percent of the convicts on the latest list "were no longer in custody." My decision about clemency was based upon the recommendation of the Parole Board in more than 90 percent of the cases," he said in a statement. A longtime GOP politician, Barbour served as the chairman of the Republican National Committee from 1993 to 1997, worked as an aide in the Reagan administration and took part in the 1988 presidential campaign of George H.W. Bush. He once had been considered one of Washington's most powerful lobbyists.
