There are going to be many, many questions about this because a lot of it doesn't make sense and doesn't fit any profile.

School shootings in particular and mass shootings in general tend to follow a particular pattern. Usually the shooter has no intention of escaping or otherwise leaving the scene. Usually they are killed at the scene either by the police or by their own hand. Some do escape but it's rare.

So this shooter allegedly escaped the scene and then a couple of days later went on to kill one particular researcher at a different college 50 miles away in what looks like it was targeted and planned.

These are two very different crimes.

And then the shooter commits suicide?

If the MIT researcher was a target, why commit a mass shooting prior? If the mass shooting was the goal, how do we explain the planning and intent of the second attack? And why wasn't that a mass shooting?

Was it the same gun in both attacks? If so, why weren't the incidents linked sooner? If they were different guns, that too raises questions.

In case it wasn't clear, the MIT attack was cased for at least 2 weeks prior.
