The death of a 4-month old suburban girl has been ruled a homicide.

Police say the child's father called 9-1-1 saying the baby wasn't breathing.

Sophia Ortiz was transported to a hospital where she later died.

An autopsy showed Ortiz suffered multiple injuries consistent with shaken baby syndrome.

Authorities say the girl was in the custody of her father at the time.

An investigation is underway.
