Four small children with signs of malnourishment and incapable of communicating were rescued on Monday from an apartment in Denver, Colo., in which they were imprisoned in unhealthy conditions.

According to the first reports made public by news network ABC, the four minors didn't know how to communicate, except by grunting and lived in a Denver house among cat and human feces, urine and flies.

Although it hasn't been verified, police authorities have added that it's possible that the children were also physically abused, reported the Denver Post in an article published on its website.

Due to these facts, the parents of the four minors have been formally accused of various abuse charges due to the unhealthy conditions in which authorities found the children, in a house full of animal feces, urine and flies, according to the Post.

The parents of the children have been identified as W. Sperling, 66, and L. Bailey, 35, who birthed the four minors of 2, 4, 5 and 6 years of age who had not received any education whatsoever and could only communicate with grunts, unable to articulate words.

Both parents have been accused of four charges of serious child abuse each, according to the Denver District Attorney's office.

According to official records, Sperling wanted to get a permit that would allow him to home-school his children. Likewise, confronted by these facts, the father of the children claimed that the house was not so dirty, although he did not admit it was clean, either.

In June 2009, both parents were pronounced guilty of child abuse, revealed the Denver Post. The four children rescued were placed in protection homes.
