She faces 25 years to life in prison when sentenced March 16 by Justice Alfred Kleiman.The toddler suffered second- and third-degree burns over half his body, with a clean line of demarcation below his waist, Associate Medical Examiner Mella Leiderman testified at the three-week trial.

Prosecutors said McKenzie held the boy in the scalding water as punishment for twice soiling his clothes that day.
