Camp Pendleton spokesman 1st Lt. Eric Flanagan said Tuesday that Maj. Gen. John Toolan decided to not send Sgt. Jason R. Byrd to court-martial after reviewing evidence in the October shooting death of Lance Cpl. Benjamin Schmidt.
The 24-year-old was the son of Dr. David Schmidt, who's a team physician with the Spurs.
Toolan is the senior U.S. Marine commander in southwestern Afghanistan.
The military has called the shooting a case of friendly fire.
