Kessinger said Anderson and Dunn confessed to having significant roles in last Wednesday's shooting, but Kessinger wouldn't elaborate about what each person did during the crime.
"That will all come out in court. We don't want to release specifics just yet," Kessinger said.
Police haven't released a motive or who the intended targets were either.
"We've had a lot of people come forward and help us with this case. We've had a lot of people not come forward. So, on the one hand, there's a lack of humanity you see in it. Then on the other hand we had people who wouldn't normally help us come forward," Kessinger said.
Anderson and Dunn are at being held at Metro Corrections on a $500,000 bond.
