Who was the first person condemned to death by a Christian bishop?

I was wondering who was the first person a bishop condemned to death, caused to be condemned to death and such sentence was approved of by said bishop and who was the first such person who was actually executed, as in being physically executed by another person without supernatural involvement, such as seen in the story of Ananias and Sapphira as recounted in the Book of Acts (Acts 5: 1-11).
