A 9-year-old girl who died after losing consciousness during a physical education class last fall died from natural causes associated with an enlarged heart, according to an autopsy report released on Tuesday, June 12.

Milagros Villalpando died Nov. 13, in Vinita.

The cause of death was listed as Myocarditis — inflammation of the heart — and the manner of death was natural, according to the 8-page autopsy report.

“Her heart was almost twice the size of a normal child’s heart,” said Amy Elliott of the Oklahoma State Medical Examiner’s Office.

The Vinita fourth-grade student, known as Milly, had no preexisting medical condition or previous illness, the report stated. The toxicology report was normal, Elliott said.

Milly had just finished playing a five minute round of basketball with a group of girls at Will Rogers Elementary School and was in a corner resting when she began to lose consciousness.

A student reported to a teacher something was wrong with Milly. After checking on the child, the teacher called 911. Initially, Milly was not talking but had her eyes open and was breathing, but she eventually lost consciousness and stopped breathing.

Emergency responders worked on Milly in the gym but were unable to stabilize her condition, and she was transported to a local hospital but reportedly never regained consciousness.

Her obituary referred to her “as a good friend who was always smiling” and she “had a heart of gold.” She was always happy and never had a bad day, her obituary read.

“Milly was a good student and had many friends there,” it read. “She loved gymnastics, dancing, singing, riding her bicycle, playing soccer, and loving on her dog Bella.”
