The man accused of shooting and killing a man in a South Park neighborhood took the stand Wednesday and defended his actions.
Chauncey Sterling is accused of shooting and killing Bob Barber two years ago while Barber walked home after getting coffee.
The No. 1 question that needs to be answered is the motive behind the shooting.
The 20-year-old told jurors he left his sister's apartment with a gun the morning of April 22, 2011, thinking he might try to rob someone for money for his two baby girls.
He told jurors he did follow Barber, but that he was so scared he changed his mind right before Barber turned around.
Sterling says Barber tried to grab the gun from him, and that is when the 20-year-old says he panicked and shot him.
"I pulled away and he lunged toward me and I fired, I don't know why, I just fired, I panicked," said Sterling.
Earlier in the day, jurors heard from Barber's wife. She told the jury that her husband had decided to get up and go get coffee with her that morning before she went to work. Then he was going to walk home for some exercise.
During her lunch break, Debra Barber says she was watching the news and saw someone had been shot. That is when she knew something was wrong.
Shortly after, police came.
"I was trying to ask him if I heard right, was it a near fatal shooting or a fatal shooting and he told me he was sorry to tell me that Bob had been killed," said Debra Barber.
