@GustavinoBevilacqua and there is also Carinus “Probably died in battle against Diocletian, likely betrayed by his own soldiers” which may count as murder, to be fair.
The previous one in the list is quite an outlier: Carus “Died in Persia, either of illness, assassination, or by being hit by lightning” so “cause of death: ALL OF THE ABOVE”? :D
