During the Guild Wars, his subordinate, a bomb technician named Isaac White, fell for a Kel-Morian bomb trap on a bridge on Gamma Dorian, resulting in a loss of Confederate troops. At Turner's command, White was demoted to private for his negligence, which was considered lenient treatment.
Turner told White he could make a difference and even atone. Turner remained White's superior officer after they joined the Terran Dominion. However, he was murdered while on leave on Bacchus Moon. He was replaced by Commander Rindge.
