Inside Susan Smith's Life Behind Bars On Twentieth Anniversary Of Her Conviction For Killing Sons

Bad behavior. At her first prison, Columbia, South Carolina's Women's Correctional Center, Susan Smith, here in her most recent mug shot, was caught having sex with two separate male prison guards.

At her next prison, Leath Correctional Institution in Greenwood, South Carolina, a former inmate named Stephanie Hulsey reveals Smith's problems only got worse.

Battle wounds. Hulsey reported that Smith "has terrible raised scars on her wrists, maybe 15 of them, some three inches long."

Suicide Attempt. Hulsey revealed that after Smith was thrown in solitary confinement for possessing prescription pills in her possession, officials caught the child killer "sitting on the floor and slashing deeply at her wrists" in a reported suicide attempt.

Painful Memories. "There was blood behind spurting everywhere and she was weeping, but she wasn't crying out in pain," Hulsey said. "She used to say, 'You don't feel pain when you cut. Cutting takes all the pain away.'"

During her years behind bars, Smith has reportedly ballooned to over 180 pounds.

Love behind bars. And Hulsey reveals the killer mom has taken another inmate lover — a convicted bank robber who, like Smith, is serving life in prison.

More victims. "Her lover is a big woman who looks like a man," Hulsey said, adding Smith also has been leading on a man she starting writing to years ago. "He's sent her thousands of dollars," Hulsey said.
