A central Illinois woman convicted in the drowning deaths of her three children is free on parole.

Illinois Department of Corrections spokesman Derek Schnapp says Amanda Hamm left the Dwight Correctional Center just after 9 a.m. Tuesday.

Hamm was convicted of child endangerment in 2006 in the deaths of 6-year-old Christopher Hamm, 3-year-old Austin Brown and 23-month-old Kyleigh Hamm. She served almost five years of a 10-year-sentence.

Hamm's boyfriend, Maurice LaGrone Jr., is serving a life sentence after being convicted of first-degree murder.

Prosecutors say Hamm and LaGrone plotted to drown the children in Clinton Lake. They claimed the deaths were accidental.

Dwight is 55 miles northeast of Bloomington.
