A 27-year-old man is accused of killing a newborn baby left in his care.
Hamilton police arrested Philip Cunningham Thursday on murder and child endangering charges.
Detectives began investigating after the 2-month-old was taken to a hospital on July 20. Doctors concluded the baby's injuries were the result of child abuse.
Cunningham was held without bond overnight at the Butler County jail. He is expected to make his first court appearance Friday morning.
