A 1-year-old child on a ventilator was killed by his father in late September, police announced Friday.
The child, whom police did not name, died on Sept. 25, police said. Police did not disclose the homicide at the time because the cause of death had not been determined, Delaware State Police said.
The child's father, Michael D. Lewis, 28, has been indicted on murder charges.
The boy was on a ventilator when he became "unresponsive" Sept. 25 and was admitted to Nanticoke Memorial Hospital.
He was pronounced dead at the hospital. Authorities deemed the child's death suspicious and began to investigate, Jaffe said.
Police said Lewis neglected to properly care for his son while he was on the ventilator. Lewis was indicted Oct. 24 on the charges of murder by abuse and first-degree neglect.
