Zane Laumer

Zane Laumer was a Starfleet ensign who served as tactical officer aboard the USS Samson (Miranda class) in 2372.

Six hours before the Samson's destruction, the ship's computer identified Laumer as being asleep on his bunk. However, a visual recording taking at that exact moment showed Laumer entering the main phaser control area. It was later revealed that the Laumer entering phaser control was a Changeling infiltrator.
