A Tri-State man is found guilty of violently shaking his finacee's two-year old son in Springboro.
Jason Milby was found guilty Thursday of felonious assault and child endangering.
The boy suffered brain damage in July 2011.
He is in a permanent vegetative state.
Milby was sentenced to eight years in prison, which was the maximum.
A jury was unable to reach a verdict in Milby's first trial in June.
