I have a question about the episode Starship Mine. When the hostage situation broke out Commander Hutchison was shot as was Geordi LaForge. We see LaForge hurt and being tended to in later scenes, but nothing got mentioned of Hutch ever again. Was he dead? Did the aliens isolate him since he was the officer in command? If he did die then why was LaForge not killed from a much closer range?
Hutch died, in the following scene we see them pulling a sheet over his body while Geordi's wounds are being tended to.
I don't recall if the same weapon was used (i.e. the same person) that shot Hutch as shot Geordi but if they were different we could argue different settings on the weapons. If it was the same alien, well, things could still work out the way they did. (Without meta-posting and calling in the man-character survives no matter what trope.)
We could argue that the impact on Hutch was on a more critical era, say the heart, than it was on Geordi (say a less vital organ.) Hutch was a middle-aged man and as I recall a bit "heavier" than Geordi. He may also have had other health issues that made him less resilient to weapons fire. I call into play "Tapestry" where Q tells Picard that if he had his natural heart he may have survived the attack that "killed" him in the episode rather than the artificial heart. So maybe Hutch had an artificial heart or other organ that made him more vulnerable to weapons fire. Where as Geordi was younger and healthier (at least going purely by body type.)
We don't strictly know what type of weapon it was or even, really, how weapons like phasers and disruptors work. We know that they're supposedly "non-lethal" weapons (unless on a high enough setting) but present-day Tasers are non-lethal too but in certain circumstances can, and have, cause(d) death.
Geordi was probably just "lucky" that the [disruptor] shot wasn't immediately fatal to him. IIRC he was suffering from his injuries and death was a possibility if not treated soon enough. Which is another factor, Hutch succumbed to the injuries quicker, again, either due to his own health or where the impact was.
