ATLANTA (AP) - Authorities are investigating how a Marietta man died skydiving in Polk County. <br />
<br />
Polk Deputy Coroner Tony Brazier said 26-year-old Donald Bragg died Saturday in an accident that also injured a second man. <br />
<br />
Emergency officials received several calls around 2 p.m. from witnesses at SkyDive the Farm in Cedartown. Brazier told The Atlanta Journal-Constitution the men may have collided immediately after jumping. <br />
<br />
The collision may have knocked one man unconscious and caused parachute malfunctions. <br />
<br />
Bragg was pronounced dead at the scene. The coroner's office did not know the identity of the injured man. <br />
<br />
The Georgia Bureau of Investigation plans to perform an autopsy on Bragg's body in the coming days. A man who answered the phone at the skydiving business said company representatives were unavailable for comment. <br />
