I compared our weapons to the victims' bodies. [ childe helped. ]

For Anders... the slash on his throat was made by a straight knife. His own knife is still the best match. A curved knife like Siffrin's probably wouldn't do it.

For Vi... the slash on her left arm could be caused by a bladed weapon, but it was probably one that's smaller than the ones we have gathered here.

I did not find a match for the hole in Vi's hand or the injury on her right wrist.

[ also here's the check, feel free to check my homework ]
