Bobby Jack Singleton was just found guilty as charged of aggravated robbery in the July 2008 beating of Jimmy Lee Dean in Oak Lawn. A jury of seven men and five women deliberated for only one hour before announcing its verdict. Singleton’s trial now moves into the penalty phase. He is facing five to 99 years. Prosecutors are expected to ask for a longer sentence for Singleton than the one given to his co-defendant, Jonathan Gunter, who got 30 years.
