Last week two women were charged with physically abusing a young boy at the home.
But now police confirm there is an ongoing investigation involving more suspects and more victims.
Monday, the grandmother of two potential victims says her own daughter sexually molested her own children at the West Valley home.
"She used to live there," says Susan Sulimowicz.
Her daughter, Stanna Sulimowicz was sentenced Monday in Davis County for sexually abusing her own daughters.
"Yes they were duct taped and were sexually molested, " says Sulimowicz.
Stanna Sulimowicz was sentenced to up to 15-years in prison for sexually abusing her children at a Kaysville women's shelter.
But prosecutors tell ABC 4 News she is being investigated by West Valley police for sex abuse of her own children while living at the home.
It's the same home were Krista Miller and Robin Rumsey lived and were charged last week with physically abusing Rumsey's son.
" Ms. (Krista) Miller, Robin Rumsey and my daughter were abusing children in the house," says Susan Sulimowicz. "Four of these children were my grandchildren.
It’s mortifying to think people where she resided could be capable of such profusely disgusting things. It makes me want to vomit."
Last week, Miller's mother came to the defense of her daughter whose charged with being accomplice to the physical abuse of the boy.
"He's been a liar," says Michelle Christensen. "I wouldn't trust that boy if he said something like that."
But West Valley police say their investigation is continuing and more victims have come forward. The spokesman for the police department also says there are more suspects involved but would not confirm that Sulimowicz is involved.
"I believe every word that boy said that he was tied up in duct tape," says Susan Sulimowicz. "My granddaughter was done the same way."
