DENVER (AP) — A Denver couple charged with child abuse for allegedly starving their four sons and keeping them in a filthy apartment are expected to enter pleas today.

Sixty-six-year-old Wayne Sperling and 35-year-old Lorinda Bailey are due in court on four counts of felony child abuse filed against them.

The boys are 2, 4, 5 and 6. All four have been placed in protective care and have undergone hospital exams that found that they could only communicate in grunts, were malnourished and were not toilet trained, according to an arrest affidavit.

The couple pleaded guilty in June 2009 to misdemeanor child abuse. Police found clutter and unsanitary conditions at the home last year.
