Box said the investigation is ongoing, and police were still at Martinez's home Friday.
Support for Martinez “has been pouring in from across the country,” Box said. “We have heard from as many as 26 kids from around the country who were kids that knew him and were foster children in his care.”
Oklahoma City police Lt. Patrick Stewart said Friday that all the boys who had been living with Martinez have been interviewed. Oklahoma City police said they conducted the investigation and made the arrest after a call was placed to DHS.
Last year, Martinez received an award for his dedication as a foster parent.
DHS spokeswoman Sheree Powell said the agency is cooperating with law enforcement and will help track down former foster children for questioning if asked to do so.
Martinez is free on $80,000 bail.
