A Georgia prosecutor says deputies who repeatedly used their stun guns on a man who died soon after the struggle will not face charges.

Chase Sherman's mother called 911 on Nov. 20 as they traveled on Interstate 85 from Atlanta to their home in Destin, Florida. She said her 32-year-old son was "freaking out" and had taken a synthetic drug known as spice.

Video from Coweta County sheriff's deputies' body cameras shows the deputies struggling with Sherman in the back of an SUV until he's still and they later realize he's not breathing. Sherman was later pronounced dead at a hospital.

Coweta Judicial Circuit District Attorney Peter Skandalakis told The Atlanta Journal-Constitution (http://on-ajc.com/2dqzdtN) in an emailed statement Monday that though Sherman's death was tragic, it is not a criminal matter.
