PHOENIX - Police say a woman arrested on suspicion of killing her young children in Phoenix told investigators that she suffocated her son and two daughters with her hands.
They say in court documents that Rachel Henry's 3-year-old son tried to stop her from smothering his 1-year-old sister.
It's unknown whether Henry has an attorney to comment on her behalf. Prosecutors say Henry acknowledged having a history of drug addiction and that her children had previously been removed from their home in Oklahoma due to issues related to her drug problem.
Authorities said Henry wasn't under the influence of drugs or alcohol at the time of the killings.
