CHICAGO (CBS) — A 29-year-old Chicago man has been charged with first-degree murder in the beating death of his 3-month old daughter earlier this month.

Ivory Harmon, of the 11300 block of South Forest Avenue, already had been charged with one count of aggravated battery to a child after he brought the unresponsive baby to University of Illinois Medical Center on Aug. 4.

The charge was upgraded to first-degree murder on Wednesday, eight days after the baby, Ianah Sherrod, died.

Harmon will appear for a bond hearing on the new charge on Thursday.

After Harmon brought his daughter to the hospital, doctors determined Ianah had been beaten and she was placed on a ventilator in critical condition after they were initially able to resuscitate her, police said. She died Aug. 9.

An autopsy found Ianah died of blunt head trauma and child abuse, and her death was ruled a homicide, according to the Cook County Medical Examiner’s office.

Harmon is already being held without bond in the Cook County Jail on the aggravated battery charge, according to the Cook County Sheriff’s office website.

The Illinois Department of Children and Family Services is also investigating an allegation of abuse, spokesman Kendall Marlowe said.
