Arizona's most notorious new prisoner is showing no remorse at all for his heinous actions, sources told the New York Post.

Jared Lee Loughner's eyes look "dead -- he's pure evil," one prison worker told a visitor.

Another person who was inside the federal prison in Phoenix, where Loughner is being held, said the madman with the ghoulish grin is living up to his image as a cold-blooded murderer.

"He's shown no remorse. No crying or anything," said Beverly Gomez, 49, who visited a relative in the prison and asked a guard about the killer. "He's segregated, but when he's out, he's, like, with six guards."

Loughner, 22, is accused of killing six people and wounding 13, including Democratic Rep. Gabrielle Giffords, whom he shot in the head, in a rampage at the congresswoman's meet-and-greet event in Tucson on Jan. 8.
