Susan Smith’s former cellmates and a prison guard who had sex with her are speaking out about the infamous woman’s checkered time behind bars.

According to Alfred Rowe, who pleaded guilty in 2001 to having sex with Smith and was sentenced to five years probation, Smith’s drug use escalated when she switched prisons from Camille Graham Correctional Center in Columbia, S.C., to Leath Correctional Institution in Greenwood.

At that point, says Rowe, “She could not longer get the male attention that she used as a drug.”

Christie Smith, her former cellmate, says Smith paid her to procure drugs.

“I’ve seen Susan do everything. Snort, booty bump, swallow, shoot. I’ve seen her do it all,” Smith says, before adding, “My main purpose was to bring her her pills.”

But it was all a lie.

As her story began to unravel, Smith admitted that there was no carjacker, and that she had let her car roll into a lake with Michael, 3, and Alex, 14 months, still strapped in their car seats.

Her motive: She was secretly dating a man who didn’t want children. The story became international news, even landing on the cover of PEOPLE. Smith was convicted of two counts of murder and is serving a life sentence. She is eligible for parole in 2024.

Twice in 2010 and once in 2015, she was disciplined on drug charges, losing privileges for more than a year.

In 2000, Smith was disciplined for having sex four times with 50-year-old prison guard Houston Cagle. He pleaded guilty and spent three months in jail. The following year, Rowe also pleaded guilty to having sex with Smith and was sentenced to five years probation.

But Smith claims she has been misunderstood.

In 2015, Smith wrote a letter toThe State. “I am not the monster society thinks I am,” she wrote. “I am far from it.”

“Something went very wrong that night. I was not myself,” she continued. “I was a good mother and I loved my boys. There was no motive as it was not even a planned event. I was not in my right mind.”
