A woman has pleaded not guilty to murder charges in the suffocation deaths of her three young children in Phoenix.
Rachel Henry entered the plea Tuesday on the charges stemming from the January 21 deaths of her three children all under the age of four years old.
Prosecutors have said that Henry has acknowledged having a history of methamphetamine addiction and that her children had previously been removed from their home by child-welfare authorities in Oklahoma because of issues related to her drug problem.
Henry’s family moved from Oklahoma to Phoenix last summer.
No motive for the killings has been determined.
