Maryland ? Investigators were trying to determine Tuesday why a woman accused of causing her baby to be stillborn had bruises on her body when she was found bleeding last week.

Police say Christy Freeman, 37, had bruises on her legs, stomach and forearm. She told police she was not pregnant, but changed her story to say she had given birth to a deformed baby, calling it “gloopity glop.”

A 26-week-old male fetus was found wrapped in a bloody towel under her bathroom sink. According to charging documents, the fetus was not deformed.

Freeman was being held without bond Tuesday, as investigators continued to excavate the grounds at her home in a search that has turned up four tiny sets of remains, including the 26-week-old male fetus.

Ocean City police spokesman Barry Neeb said interviews with Freeman led police to believe she caused the stillbirth. They also have not said whether they believe she was responsible for the other three sets of remains.

Freeman was charged with murder under a state law that allows murder prosecutions of those who cause the death of a fetus that may have been able to survive outside the womb.
