VEEDERSBURG, Ind. A couple who ran a baby-sitting service out of their home videotaped themselves performing sex acts with children, some as young as 2 months old, police said Friday.

Stephen E. Quick, 31, and Samantha Light, 25, both of Veedersburg in western Indiana, were being held on $100,000 bond in Fountain County Jail. Both faced preliminary charges of child molestation and child exploitation. Jail staff did not know whether either one had an attorney.

Police who searched the couple's home found a videotape depicting sex acts involving Quick and Light and at least four different children between the ages of 2 months and 6 years old, said Fountain County Sheriff's Deputy Bob Kemp.

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

Police searched the couple's home after the parents of a 3-year-old girl reported that she told them Quick and Light had touched her inappropriately and photographed her at their home on Feb. 28.

Deputies seized several computers, cameras, a video camera, pornographic materials, drugs and drug paraphernalia. Several sex toys that appeared in the video were seized during a second search, police said.

Quick and Light were arrested March 5. Neither has a criminal history.

Authorities have removed the couple's daughter from their home.
