Joshua 8:24, 28-29

During the fighting the army of Israel chased the men of Ai into the fields and desert and killed all of them. Then they went back to Ai and killed everyone there.

Then Joshua burned the city of Ai and made it a pile of ruins. And it is still like that today. Joshua hanged the king of Ai on a tree and left him there until evening. At sunset Joshua told his men to take the king’s body down from the tree and to throw it down at the city gate. Then they covered it with a pile of rocks, which is still there today.
