The Jacksonville Sheriff's investigators arrested 56-year-old Darryl Allyn Ewing, who was accused of neglecting a child on Wednesday night, hours after the baby was found in a van parked in front of the Ewing Love and Hope Center.
The baby's mother called the center around 1 pm and an employee said that she did not know that the child was there. Officials say the employees then found the baby in the van.
She was pronounced dead at the hospital.
Sheriff's officials said Ewing refused to talk to the detectives. He remained in jail on Thursday morning.
