Here's a summary of what you found from examining the scans of the alien captain's body:

Aurin-Ahs concentration pays off as he finds the key to interpreting the alien presentation of data. He's seen many ways to show such information, and while this is new, it slowly makes sense to him.
As he focuses and learns the method employed by the aliens, he comes to understand that he's seeing a medical scan of the murdered captain, along with analysis. The anatomical displays show the point of entry of a small object. The edges are clean without tearing, such as from a sharp cutting instrument. Other than that, the hormonal balances are shown to be within expected tolerances, save for adrenaline and fear which indicate that the captain was aware of the danger, but died before he could fight back. (There are no defensive wounds suggesting he got any hits in.)
The unusual part comes from a materials analysis of the murder weapon. Tiny shards of crystallized metal were examined from microscopic fragments in the wound. It's a composite metal-ceramic implement that is likely extremely high tech, even by the Federation's standards. It would not be inappropriate to say that it's 'cutting edge' materials science.
