Three members of a foster family have pleaded guilty to abusing children, including several who previously were tortured by their parents in a Southern California home.

The Press-Enterprise reports that Marcelino Olguin pleaded guilty Thursday to multiple counts of lewd acts on a child in addition to false imprisonment and injuring a child. His attorney, Paul Grech, said he entered the pleas in Superior Court in Riverside to bring closure to his family.

Olguin’s wife Rosa and daughter Lennys pleaded guilty to child cruelty, false imprisonment and other charges.

Among the children they cared for were six members of the Turpin family, who were placed with the Olguins after being rescued from horribly abusive conditions in their parents’ home.
