The Portland baby hospitalized for head injuries last month after police said he was beaten and thrown by his father has died.
The 11-month-old passed away this week.
His parents, Thomas Snelling and Jeanie Tate, who already face child abuse charges, could now face murder charges.
Police said Snelling confessed he slammed the infant's head into the crib and threw him across the room because he wouldn't stop crying.
The state conducted an autopsy on the boy Thursday.
