DENVER (AP) -- A Denver couple accused of starving their four sons and keeping them in squalid conditions are due in court to face charges Tuesday morning.
Wayne Sperling and Lorinda Bailey have each been charged with four counts of felony child abuse
The boys are 2, 4, 5 and 6. An affidavit says they weren't toilet trained, had no schooling and spoke in "their own language" of grunts to each other.
Authorities found the children living in a residence full of cat and human feces, urine, and flies. All have been placed in protective care.
The couple pleaded guilty in June 2009 to misdemeanor child abuse, according to the affidavit first obtained by KMGH-TV (http://goo.gl/4uGf48 ). The ABC affiliate also reported that police found clutter and unsanitary conditions at the home last year.
