A Massachusetts woman charged with two counts of murder after the skeletal remains of three babies were found in her squalid home faces arraignment.

Thirty-one-year-old Erika Murray is scheduled to be arraigned Monday in Worcester Superior Court. Murray originally was charged with fetal death concealment after the remains were found in her Blackstone home in September. She pleaded not guilty and was held on $1 million bail. She was indicted on the murder charges earlier this month.

The house was infested with rodents and insects, piled high with dirty diapers and contained dead animals. Workers in hazmat suits spent days cleaning out the house, which later was demolished. Murray's lawyer has said she has mental health issues and there's no evidence she caused the deaths of the babies.
