Michele Kalina pleaded guilty to murdering one of her infant children after the skeletal remains of five babies were found in her home. Michele Kalina, 45, expressed remorse at her sentencing but has not confessed to killing all five newborns she gave birth to secretly. A Berks County judge sentenced her to between 20 and 40 years in prison.

In July 2010, Kalina's husband and teenage daughter discovered containers in a storage closet in the family's Reading, PA home that contained the remains of five infants. They were found in storage containers and an insulated cooler, according to court documents.

"One body was encased in concrete," Berks County District Attorney John Adams said. "It was a very bizarre case. The others were wrapped in garbage bags." The skeletal remains were estimated to be from 32 weeks in gestation to newly born. "There were five skeletal remains, but because of the condition of those skeletal remains it was very difficult to determine a cause of death. But we had enough information to charge her with one body," Adams told ABCNews.com.

In addition to the third degree murder charge, Kalina was found guilty of abusing the corpse of an infant and failing to report the death of a child.
