The mother calling police dispatch was distraught.

“My baby’s dead. I think she choked on milk,” the woman said, according to an initial investigation report from the Milwaukee County Medical Examiner’s Office.

When emergency responders arrived at the home Friday, they found a 20-month-old girl, with CPR already underway. But attempts to revive the child, Kyleeh Mazaba, were unsuccessful; she was pronounced dead at the scene.

“It’s just heart-wrenching,” Harriet Hill, a neighbor, told the local Fox News affiliate. “Kyleeh was quiet. She was a wondrous type of child — big, round, beautiful eyes. She seemed like a really wonderful kid.”

Milwaukee police are investigating the toddler’s death.

Authorities are still waiting on toxicology reports before releasing an official cause of death. That process should take about eight to 10 weeks, the Medical Examiner’s Office said.

The medical examiner’s investigation report does provide some information, though.

Authorities were told, for example, that before the girl died, she had ingested some of her mother’s methadone.

The child’s mother told authorities that she hadn’t used heroin for seven years, according to the medical examiner’s office report. She told them that she took methadone, a medication for patients dealing with withdrawal.

“She stated that she keeps her Methadone locked in a safe or out in her car,” the report notes. “She denied the possibility of Kyleeh getting into her medications because she puts them in her purse and hangs the purse on the top of a door.”

The day after her daughter’s death, however, the mother called an investigator and said that her 8-year-old son later told her that Kyleeh drank the medication.

The woman said that she had poured some of it into an empty water bottle, which was in the family’s van. Kyleeh drank it while she was in the van with the boy, the son told his mother.

“The mother was crying and upset and she wanted to know if she was going to be arrested,” the report notes.

The woman told investigators that she was the mother of eight, according to the report, which added: “She has had no other children die.”
