What was Achan's punishment for taking the accursed thing during the Jericho massacre?

He and his family were stoned to death and then burned.

Joshua, and all Israel with him, took Achan the son of Zerah, and the silver, and the garment, and the wedge of gold, and his sons, and his daughters, and his oxen, and his asses, and his sheep, and his tent, and all that he had: and they brought them unto the valley of Achor.

And Joshua said, Why hast thou troubled us? the LORD shall trouble thee this day. And all Israel stoned him with stones, and burned them with fire, after they had stoned them with stones.

And they raised over him a great heap of stones unto this day. So the LORD turned from the fierceness of his anger. Joshua 7:24-26
