Medical examiner: Mount Prospect baby died from abuse

Mount Prospect police are investigating the death of a 6-month-old boy as a homicide, authorities said Sunday.

Zayden Chavez was pronounced dead at 10:59 p.m. Thursday at Lurie Children's Hospital in Chicago.

An autopsy performed by the Cook County medical examiner's office Saturday revealed the baby died of complications from multiple injuries due to child abuse.

The medical examiner also classified his death as a homicide.

Mount Prospect police officer Greg Sill said the department is investigating a case involving an infant that occurred Oct. 28 in a Dempster Street home. Police did not elaborate.

"Our investigators are now actively investigating this incident as a homicide at this time," Sill said.

The Illinois Department of Children and Family Services also is investigating the baby's death, spokesman William McCaffrey said. DCFS has had prior contact with the family, McCaffrey said via email, but he declined to provide further information, citing the ongoing investigation.
