Reminds me of this story from last year, including:

"Later on Tuesday, SPA quoted a third statement saying that Sa’ad Al Mansuri, a Saudi, was beheaded in the central city of Buraida after he was convicted of shooting dead a fellow citizen, Munif Al Maqati, with a machinegun “following a dispute between the two”."

At least he wasn't a teen.
