EAST LIVERPOOL Deputy coroner says boy died of a head injury

The boy was hurt at home twice before a fatal injury, authorities said.
EAST LIVERPOOL -- A 3-year-old St. Clair Township boy with a history of being hurt at home died of a head injury, the Allegheny County coroner's office determined.
What's unclear is how those injuries occurred, Ken Suchan, a deputy coroner, said today.
Dalton Springer died Nov. 16 in Children's Hospital of Pittsburgh, where he was taken Nov. 12 after being hurt at his Sidehill Road home.
The coroner's office determined that blunt force was administered to the boy's head. But they were unable to ascertain how, or with what, Suchan said.
Dalton's mother, Tiffini Marcum, and his stepfather, J.C. Marcum, told authorities the boy fell out of bed, said assistant Columbiana County Prosecutor Tim McNicol.
Neither adult is charged in Dalton's death.
Including the fatal injury in November, Dalton had been treated three times in 2000 for injuries suffered at home, according to the prosecutor's office.
He was treated for a broken arm, which his parents said occurred when he jumped or fell into an entertainment center. Dalton also was hospitalized for a punctured stomach and bruised penis, the result of a fall, his parents told investigators.
