The death of a three-week-old girl from the West Englewood neighborhood was ruled a homicide Saturday afternoon by the Cook County Medical Examiner's office.
An autopsy determined that Emonie Beasley-Brown, of the 3900 block of South Wells Street, died from suffocation, the medical examiner's office said.
After hearing the autopsy results, police launched a homicide investigation, according to police News Affairs Officer Darryl Baety.
On Thursday, Beasley-Brown was pronounced dead at the University of Chicago Medicine Comer Children's Hospital at 10:35 p.m. after she had been suffocated in the 5900 block of South Loomis Boulevard, the medical examiner's office said.
A spokesman for the Illinois Department of Children and Family Services said on Friday that the agency was investigating allegations of abuse against Beasley-Brown's mother and great-grandmother.
DCFS spokesman Jimmie Whitelow said the agency had previously investigated "credible allegations" that the baby's mother had been abused as a minor.
In 2003, DCFS looked into allegations that the mother had been abused by her mother's boyfriend, Whitelow said. The agency also looked into 2011 claims that a male relative was abusing the mother, who was a minor at the time.
No other children have been removed from either the home on Wells Street or the one on Loomis, Whitelow said.
