(CNN) -- A Pennsylvania woman was charged Monday with criminal homicide after forensic tests showed her to be the mother of four infants whose remains were found in her home in July, according to Berks County, Pennsylvania, District Attorney John Adams. "We may make the determination that we will charge her with four separate counts," Adams said. Kalina's lawyer, Assistant Public Defender Holly Feeney, declined to comment on the case. "However, this is a very unusual case and frankly we're going to have to discuss this with our forensic pathologist." According to the statement from Adams' office, the pathology report indicated four of the deaths were, "consistent with asphyxia, poisoning, or neglect." Remains of a fifth infant were found Aug. 6 in the Conestoga Landfill, New Morgan, authorities said. Adams said DNA testing matched her positively to four of the five remains and a man Adams described as her boyfriend to three. Later that day, officers recovered the suspected remains of three infants from Kalina's apartment. "One of the containers contained an amount of cured cement, which was later determined to have encased the remains of one of the infants." Detectives later recovered a fourth set of infant remains at the house, and found a bone believed to be from a fifth set of infant remains in a landfill. Kalina's teenage daughter first contacted authorities on July 29, unsure of what she had discovered in the living room closet, Adams told CNN. "We have not spoken to anyone who came forward and said they have seen her pregnant," Gombar said.Kalina initially was charged on Aug. 9 with abuse of a corpse, following the discovery of remains in a closet of the family's Court Street apartment.Following a 21/2 month investigation, Kalina was charged additionally with a blanket charge of criminal homicide in the five deaths.Adams said that prosecutors will determine before trial the number of homicide counts.
– A Pennsylvania woman successfully concealed five pregnancies from both her husband and the man she was having an affair with before killing the infants and hiding their bodies, say prosecutors. Nurse's aide Michele Kalina has been charged with criminal homicide in the deaths of the babies, whose remains were found in her home and in a landfill site, CNN reports. DNA testing has established that she is the mother of at least four of the infants, and her boyfriend is the father of at least three. All five of the babies were born during the 14 years Kalina was having an affair. She was arrested in August after her teenage daughter found the remains of an infant in a closet in the family's home. "Nobody knew she was pregnant," the district attorney told the Reading Eagle. "I've been involved in the criminal justice system for 25 years and this is the most bizarre thing I've heard." He says pathology reports show that four of the deaths are "consistent with asphyxia, poisoning, or neglect."
