Sixty-year-old Gilbert Conway is heading to trial on more than 80 counts of kidnapping, torture and rape allegations brought by seven women. Since this case first surfaced in July, three more women have come forward.

After investigators arrested Conway and searched his house, they found the most disturbing evidence on video tapes.

“There are somewhere in the neighborhood of 400 to 500 tapes,” said Genesee County Prosecutor David Leyton.

Sources are telling 7 Action News that Conway’s home had a bedroom that was set up as his personal video studio, with a small camera on a tripod and a bed where he imprisoned his victims for several hours at a time.

Sources also say he may have drugged them.

“He would tape them. He would torture them. In at least one stance he would ******* on them," Leyton confirmed. "These are terrible, terrible crimes that are almost unspeakable. But we have to bring it to light so we can get justice for these victims.”

Investigators have to convert the video tapes to digital video and pictures. They will work to identify more women and find them. The pictures may also be put out in the media.

“If channel 7 Action News shows this in Detroit, perhaps we’ll be able to get some more victims to come forward,” Leyton said.

Investigators are not ruling out some victims may have been killed.

Conway’s defense attorney says some of the women in the videos may be prostitutes who were paid.

But as many as 10 women could be telling their story to a jury in Flint in the next year.
