An arrest affidavit reveals new details in the tragic death of a 6-year-old Arkansas boy, whose mother has been arrested after his body was discovered under the floorboards of his family’s home, according to recent reports. 

Ashley Rolland, the boy’s mother, and Nathan Bridges have been charged with his murder after Bridges allegedly drowned the child in a toilet, the affidavit obtained by affiliate FOX 13 states

The affidavit, released by the Lee County Circuit Court clerk, details how a grandmother’s report of concerns for the young children in their mother’s care led to the devastating discovery last week.

According to FOX 13, Karen Rolland asked that the Lee County Sheriff’s Office check on her daughter’s Moro, Arkansas, home on Front Street. Deputies responded and Ashley Rolland, Karen’s daughter, allegedly told them the boy was not there. 

Meanwhile, the child’s sister, also 6, was found to have had suffered serious burns and scabs on her scalp, FOX 13 and police reported. The girl was taken to a local hospital for treatment.

But Ashley Rolland later called the sheriff’s office to say her son was not at the home.

Lee County officials later notified Arkansas State Police Criminal Investigation Division.

The Arkansas State Police said in a Dec. 17 press release that the victim is believed to have died "from injuries sustained in the home, possibly three months ago." 

According to FOX 13, the victim bit Bridges’ hand, which allegedly prompted Bridges to drown him in the bathroom toilet.
