ONTARIO – A 24-year-old Ontario man was arrested and lodged in the Malheur County Jail last week and charged with causing the death of an infant.

Sergio Manuel Diaz faces charges of criminal negligent homicide and first-degree criminal mistreatment - both felonies - and his bail was set at $100,000, said Dave Goldthorpe, Malheur County district attorney.

Goldthorpe said police were called after the mother of the infant, Lizette Fierrof, 23, Ontario, brought the child to the Saint Alphonsus Medical Center Ontario before midnight Nov. 24.

Goldthorpe declined to provide many details about the incident, the sex of the infant or the injuries to the child because it is still under investigation.
