CENTER, TX (KTRE) - A grand jury is still listening to witness testimony in the Shelby County capital murder case.
Former sheriff's deputy Rex Calhoun and his wife, Lana Sue, are charged in the brutal beating death of Rex's brother, Alan Calhoun.
As Joe Calhoun waits to testify in front of a grand jury in his uncle's capital murder case, questions about his father's alleged involvement weigh heavily on his mind.
"What's upsetting to me is he's my Dad. I'm up here, I'm having to help get justice for my uncle," said Joe Calhoun, Rex Calhoun's son.
The death of Alan Calhoun, 56, was ruled homicidal violence, including blunt force trauma.
"I wish my dad would have took up for my uncle," said Joe Calhoun.
According to the Shelby County District Attorney's Office Chief Investigator Kevin Windham, Alan was mentally disabled and severely abused over an extended period of time. Joe Calhoun believes the abuse, both verbal and physical, started from the day his uncle moved in with the couple in 2008.
"I didn't like the situation, I knew she was going to be mean to him, but I really thought my Dad would take care of him," said Joe Calhoun.
Amid the disappointment and betrayal, he says he never thought it would come to this: his uncle dead and buried with a nameless grave marker. It's been eight months since Alan Calhoun was buried, and his nephew still has countless unanswered questions.
"We just don't know any answers right now as far as if he was there or not," said Joe Calhoun.
More uncertainty lies ahead, as his father and stepmother's future hang in the fold.
"My life has changed because Alan is gone," said Joe Calhoun.
Witness testimony could go on until Friday morning. We'll update you if an indictment comes down.
