it was a civil war in the saudi royal family, the shooting was the coverup or stray bulletse.

the only thing we can know for sure about it is that someone tried to kill the saudi prince who was about to take over, and he took over, then arrested the rest of his family, and after all of this they are closer to israel than ever and are waging a brutal war against civliians in yemen, which is a proxy war against iran, and illegal in every way, just like what the us usually does, who is also arming the conflict from a distance.
