( Hamilton, OH ) - 20-year-old Dylan Tompkins was arrested last month for allegedly shaking, squeezing and slapping 1-year-old Bryce Pelfrey. This week, a Butler County grand jury upgraded those charges to murder.

On August 2, police responded to an apartment on Marilou Drive in Hamilton when they received the report of a baby not breathing. The child died two days later from what police said were inter-cranial head injuries.

Tompkins is currently being held on a $150,000 bond in the Butler County Jail.
