Police say the mother of a baby found dead at a Detroit-area recycling center had three other children but lost custody of them.

Roseville Chief James Berlin says the 24-year-old woman is expected to appear in court Wednesday in Eastpointe. He says a "sick story" has "become sicker" as investigators learn more about the death of the newborn.

Berlin says the boy was born around Dec. 22 and died two days later. He says the body was left in a shed in Eastpointe and somehow ended up at a recycling center nearby in Roseville on Jan. 14.

Investigators initially believed the baby might be a missing child from the Lansing area, but tests ruled it out.
