A Fall River Superior Court Jury has returned guilty verdicts against a father and son from Acushnet related to the beating of a Taunton man who was left with permanent injuries. 

According to the District Attorney's Office, 55-year-old Christopher Adams and 28-year-old Jacob Adams were found guilty of unarmed robbery, assault and battery with a dangerous weapon and assault and battery, but they were acquitted on the most serious charge, assault and battery resulting in serious bodily harm. 

Prosecutors say the father and son beat 27-year-old Gary Medeiros in May 2011. Medeiros had dated Christopher Adams' daughter and the father and son thought he had stolen $1,900 from their home.  Medeiros requires round-the-clock care and is unable to walk or talk. 

A defense lawyer said the Adamses used ``reasonable force'' to retrieve stolen money.  Sentencing is scheduled for February 26th.
