It can be hard to take VNs too seriously. For example, blood tends to dry a bit quick on cloth. If they examine things more closely they will realize the only bit of blood on the MC is what dripped on his shoulder. If he got him from behind then trying to make that kind of gruesome cut on someone taller than you would be very hard especially if he had to close Raynar's muzzle shut to do it silently. I also feel like he seen this coming which is why he asked the MC to be there for his kid; Maybe they will find something like a note that exonerates him? Because it makes no sense to murder a king for no reason in silence and then tumble as youre running out of there like a total clutz and not a ninja. The dagger or whatever it was was also left at the scene. I think a sniff at it with a wolf species will be able to tell it wasnt touched by Richter. Maybe the design of it would be recognizable, maybe to Lyall if it belongs to that reptile assassin. Why else would it be left at the crime scene if the murderer wanted them to know who done it? [Unless they intended to frame MC from the beginning. In which case we dont have enough info on who the culprit is other than who may have planned it but not did it. If this VN made any sense at all it wont be someone short, weak, or unable to climb/fly like Lief, Liz, or Kadaj. And Adrius will just be another victim here, maybe puppeted. Kadaj as well. He must have seen this coming somehow. Whoever it is is trying to drive a wedge between Lyre and other kingdoms. Someone wants the throne methinks or just to really destabilize Lyre which is perfect for bandits to operate from if the kingdom becomes corrupted. It is all conjecture and we wont know what really happens in this story though. It is up to Atmac and his imagination].
