Authorities had problems with Tyesha Hamilton for years.
While the mother of four dealt with a drug addiction in 2007, her daughter Alexandria and her three siblings were taken from Hamilton's custody.
After cleaning up her act, Hamilton, 30, got her children back, but the trouble only became more horrific, going from drugs and neglect to senseless abuse and murder.
In February, paramedics found her 2-year-old daughter Alexandria unresponsive.
She was burned badly, and authorities believe that Hamilton immersed young Alexandria in a tub of scalding water after "she soiled bed sheets."
Alexandria died from her injuries.
Yesterday, Hamilton pleaded guilty to her murder and was sentenced to life in prison with the possibility of parole after 15 years.
