Defense attorney Sonny Cribbs said if there was any doubt that Granger fired the bullets that killed Sebolt, he should not be found guilty of a capital crime.
"Our position is he's not guilty of capital murder," Cribbs told jurors. "He might be guilty of murder."
On Monday, Granger and Shettle engaged in feisty back and forth during cross examination, with Granger finally asking the prosecutor why he was so hostile.
"What did I do to you?" Granger asked.
"That little old lady bled to death," Shettle replied. "That's why there's such animosity."
Prosecutors say Granger was furious with his daughter, her mother and his estranged wife because they had testified against him in the sexual assault trial. He illegally bought an assault rifle from a Houston gang member then waited outside the courthouse in his truck for hours to take his revenge, prosecutors said.
Granger said the events of the day were hazy, but then went on to describe in detail how his daughter fell, how she cried for him to stop and how he repeatedly pulled the trigger then ran back to his truck and drove over her.
