FOUNTAIN COUNTY, Ind. -- "Horrible" is how Fountain County authorities describe the actions of two people accused of videotaping themselves performing sex acts with several children as young as 2 months old.

Stephen E. Quick, 31, and Samantha Light, 25, both of Veedersburg, were arrested on March 5 after a young girl told her mother that the couple had touched her inappropriately and photographed her while she was being baby-sat at their home on Feb. 28.

"I asked her if they were just helping her in the bathroom and she said, 'No mommy, they took pictures," the girl's mother, who wanted to remain anonymous, told 6News' Jack Rinehart.

Deputies seized several computers, cameras, a video camera, pornographic materials, drugs and drug paraphernalia during an initial search of the couple's home, said Fountain County Sheriff's Department Deputy Bob Kemp.

They also found a videotape that showed several sexual acts involving both Quick and Light and at least four different children between the ages of 2 months and 6 years old, Kemp said.

Several sex toys that appeared in the video were seized during a second search of the couple's residence, police said.

"In 15 years of doing this job, it's the worst thing I've ever seen or imagined," Kemp said. "Just horrible, just horrible … It's a new low."

Light was later arrested at the home, while Quick was arrested at his work. They had been running a baby-sitting service out of their home, police said.

Former family members of Light said they were shocked by the accusations. They described her as intelligent and controlling.

"It makes me want to cry reading that stuff because those children, those poor children. And that little baby that had no idea what was happening to it," the woman, who did not want to be identified, told Rinehart.

Neither Light nor Quick have a criminal history.

The mother of the 3-year-old girl said she wants them to be put in prison for life.

"The damage they have done to these young children is going to affect them for the rest of their lives. And there's no taking back what has happened already," she said. "All they can do is make sure that it never happens again."

Quick was preliminarily charged with three counts of child molestation and one count of child exploitation. Light faces four counts of child molestation and one count of child exploitation.

The couple's young daughter has been removed from the home.
