In the newly released video, the SCSO deputy is seen running after Kirkwood. When Kirkwood turns around, he is seen lunging – swinging his arm at the deputy.

The deputy then stumbles back and Kirkwood walks toward him, and the deputy then is seen firing shots at the suspect.

Kirkwood's niece told FOX13 the use of deadly force was unnecessary.

"They tazed him and then maced him," said Mia Kirkwood. "They didn't have to shoot him. It is messed up to me, it is hurting me. I have been crying all day about it."

However, retired SCSO deputy Mike Collins said the officer had "no other choice" but to use deadly force.

Collins told FOX13 that if TBI agents find evidence that the deputy tried to use his Taser or Mace before firing his gun, the shooting will be ruled as justified.

"He did everything. He almost went textbook in the application of the force continuum," Collins said.
