Medford police have identified the mother of a baby girl whose body was found Saturday in a garbage bin at the Holiday Inn Express in Medford.

A person who saw the pregnant mother in the area of the bin before and after the baby was discovered by a homeless man sifting for recyclables contacted police detectives Sunday night.

Based on information the witness provided, police were able to locate the 19-year-old mother at about 9 a.m. today at her home.

"She provided us with a statement, which outlined her version of what occurred," said Medford police Detective Sgt. Mike Budreau. "We can't confirm that until we have the results of the autopsy."

An autopsy of the baby is set for 11 a.m. Tuesday. It is expected to take two to four hours to complete, Budreau said.

Budreau declined to disclose the mother's version of the story, citing the open investigation. Police are now interviewing the woman's friends and family and are trying to find the baby's father, he said.

The woman lives with her mother in Medford and has no other children, Budreau said. It's unclear whether she is employed, but she is not enrolled in school, he said. Her name is being withheld to protect the investigation, he said.

The female witness had seen the women in the area of the garbage bin while she was still pregnant and again later after the baby had been discovered, he said.

Police knew how to find the woman because they interviewed her before the witness came forward, he said.

"Now we know the who part," Budreau said. "Now we are still trying to find out the what and the why part."
