Police would not comment on what investigators were searching for, but said because of the size and complexity of the crime scene they have asked the FBI's Evidence Response Team to assist in collecting evidence.
"Investigators have still not completed their search of the property. They are still actively searching for additional evidence in this case," police said in a statement Sunday.
Christy Freeman, 37, lived in the apartment with her boyfriend and her four other children.
Freeman was hospitalized Thursday and police were called after medical personnel determined she had been pregnant, but the child was missing. Police said they obtained a search warrant for Freeman's home after interviewing her, and a small body was found wrapped in a blanket in the apartment.
Police said Freeman was later charged with first degree murder, second degree murder and manslaughter after investigators conferred with Worcester County State's Attorney Joel Todd.
Freeman, who had an initial appearance Friday evening before a District Court Commissioner, is being held at police headquarters until a bond review hearing Monday morning, police said.
