According to court documents released Tuesday evening, officers were called to the scene after an unidentified woman called to report three kids who were found dead inside the home.
During a police interview, a person acknowledged that Henry had a methamphetamine addiction, and had been acting strange over the past several days. The person's name was redacted in court documents.
Police say Henry admitted during an interview to smothering each of the victims, starting with the one-year-old girl.
Henry told police she was playing with the one-year-old and wrestled on top of her. Henry felt the one-year-old's breathing was obstructed but continued to impede her breathing by placing her hand over the one-year-old's mouth.
Investigators allege the one-year-old kicked as Henry smothered her, while the three-year-old boy yelled "no" at Henry to try to get her to stop. The three-year-old then punched Henry in an effort to help the one-year-old. The one-year-old eventually stopped kicking Henry, which is a sign to Henry that the girl has died.
Henry, police allege, later chased the three-year-old boy, but was interrupted when two people returned to the home.
Shortly after a person, whose name was redacted in court records, spent some time playing with the three-year-old, Henry reportedly took the boy into a back bedroom, where she changed his underpants.
As Henry changed the three-year-old's underpants, police say she placed the boy on the bedroom floor, straddled him with one of her legs, and placed her hand over his nose and mouth.
Officials say Henry described singing to the boy as he scratched her chest and pinched her while she placed her hand over his nose and mouth. Henry also used her weight on top of the three-year-old, straddling him, in order to smother him to death.
As for the seven-month-old, police claim that Henry fed her until she fell asleep, and sang her a song as she placed her hand over her face and impeded her breathing. Henry sang to the seven-month-old until she became unconscious and died.
Investigators claim Henry placed all three children in a position on the living room couch as if they were taking a nap.
