The parents of a 5-year-old Virginia boy face charges of abuse and neglect after their son’s body was found in a septic tank.

Paul Thomas and Ashley White were reportedly in court this afternoon. They were arrested Thursday, one day after their son Noah’s funeral.

Police say Noah went missing on March 22 while his mother napped with her infant daughter. His body was found March 26 in the septic tank on his parent’s property after a search effort which involved dozens of law enforcement agencies.

Authorities don’t know how Noah died and are still working on his autopsy.

Noah’s parents face abuse and neglect charges related to both Noah and their infant daughter, who has been taken from their custody.

Police say they got a hard and credible tip that they needed to look inside the 1,000-gallon septic tank behind the family home.

Montgomery Sanitation Services out of Christiansburg was called to drain the septic tank. We tracked down the technician, who said he was in Giles County when he got the call.

Sheriff Jim Davis, through the Pulaski County public information officer, said that FBI agents and Pulaski County investigators had already removed the two-pound plastic lid. They saw sludge, put the lid back on, and called the company to come drain the tank. We asked the technician what he did when he got to the home.

"Went down to the property, seen two police officers there. And they showed us where the tank was,” Montgomery Sanitation technician Jonathan Abate said. “And we started pulling our hoses off just like we would a normal job. And we pulled the lid off the tank and start pumping. And that's when I seen the little boy down there."

Abate said the septic tank where he found Noah Thomas was about 4 feet wide, 8 feet long and 5-and-a-half feet wide.
