Cool story so far! One spelling mistake I noticed on panel 6 of the final page - missing the y from parapsychologist. Shame on your artist for adpopting the Star Trek Online version of Saurians instead of the 'true' Saurians from TMP! It was a nice nod though and we can add northern and southern Saurians to our northern and southern Trill
If I had to hazard a guess at this stage - the woman did it. It's TAS - no point in having a woman in the episode unless she's a love interest or a killer or both.
