Dad with "sole care" of 5-month-old son arrested for child abuse; baby has severe head trauma (Washoe County, Nevada)

Notice that the baby was in the "sole care" of his father when his head was bashed. Unnamed
"family members" took the baby to the hospital.

There is no mention of the baby's mother, either in the home or elsewhere. Is MICHAEL HERNANDEZ a single father? What happened to Mom?

A man was arrested last week after his infant son suffered severe trauma to the head, the Washoe County Sheriff’s office said.

Michael Hernandez, 20, of Cold Springs was booked Wednesday on one count of child abuse causing substantial bodily harm. His bail was set at $20,000.

The incident was reported Feb. 21 after Hernandez’s five-month-old son suffered injuries to his head, deputies said in a news release.

Deputies said Hernandez was in sole care of his son at the time of the injuries, launching an investigation leading to his arrest.

Family members had taken the infant to a local hospital for treatment. The condition of the child was not immediately known Monday. Deputies said the investigation is ongoing.

Anyone with information is asked to contact the Washoe County Sheriff’s Office Detectives at 775-328-3320 or Secret Witness at 775-322-4900.
