HARRISON – A Mill Street woman was charged with murder Friday two months after her infant son died inside their home.

State police arrested 43-year-old Pamela Henderson and charged her with murder for the death of her 3-month-old son Zachary.

On March 5, police were called to the Henderson home at 12 Mill St. after receiving a report that the child had drowned in a tub and that his mother was hysterical.

According to court records, the baby’s father told police he had received a phone call from Henderson the night Zachary died and that she had stated: “I’ve done something bad … I’ve killed the baby.”

The father, James Storey, also told police that when he arrived at the apartment, he found Zachary dead in his crib, fully clothed and dry. Henderson, he said, was sitting on a couch, also dry, and with a bandage on her wrist.

Police said Henderson cut her wrist and took pills shortly after the baby died. She was later hospitalized.

According to court documents, Henderson told police she had fallen asleep in the bathtub with her child. She told them she awoke to find Zachary dead beneath the water.

Police and the Attorney General’s Office continued to investigate the death. With a warrant, they searched Henderson’s home March 6 and seized several items. Among them, several baby blankets from the crib; wet towels from a hamper; damp baby clothes; a baby bottle with formula; two cellphones; medical, financial and telephone records; a computer; a handwritten note; a knife and pills.

This week, police and prosecutors convinced a Cumberland County grand jury that there was evidence of murder in the death of the infant.

Henderson was indicted on that charge Friday morning. About 1:30 p.m., police detectives found Henderson at a friend’s home on Edes Falls Road where they arrested her.

Henderson was taken to the Cumberland County Jail in Portland where she is expected to remain at least until Monday or Tuesday when she makes an initial court appearance.

An autopsy on Zachary Henderson was completed by the State Medical Examiner’s Office, but the cause of death has not been disclosed.

Days after Zachary died, neighbors held a vigil in the boy’s honor in front of the Mill Street home. They said Henderson had been living in a second-floor apartment with Zachary and a 17-year-old daughter, who was not home the night the infant died.
