The parents of a Destin, Florida, man who died after Georgia sheriff's deputies repeatedly used stun guns on him have filed a federal civil rights lawsuit.

Kevin and Mary Ann Sherman's suit says Coweta County sheriff's deputies Joshua Sepanski and Samuel Smith, as well as EMT Daniel Elliot, violated the civil rights of their son, 32-year-old Chase Sherman.

Mary Ann Sherman called 911 on Nov. 20, 2015, from Interstate 85. She said her son was "freaking out" and had taken a synthetic drug known as spice.

Video from the deputies' body cameras shows them struggling with Sherman in the back of an SUV until he's still and they later realize he's not breathing.

A lawyer for the sheriff's office declined comment. The fire department didn't immediately respond to requests for comment.
