CHICAGO (AP) — A Chicago woman whose conviction in the death of her 4-year-old son was overturned by a federal appeals court has been released from prison.

The Illinois Department of Corrections says that Nicole Harris was released from Dwight Correctional Center on Monday at noon.

Harris had been in prison since 2005 after being convicted of strangling her son with a bedsheet. In October, the 7th Circuit U.S. Court of Appeals overturned the conviction of Harris because Harris' 6-year-old son was wrongfully prevented from testifying that his brother's death was an accident.
