Another one

Curious. The would-be assassin went to CalTech for his undergrad (I didn't get in), but for grad school went to Cal State Dominguez Hills, which has high rankings for "Hispanic enrollment" and "social mobility" but which I have never heard of before. I gather he worked on engineering a wheelchair brake, but so far haven't found any reliable details. Changing majors between degrees makes sense--sometimes you don't know how it really is to work in a field until you try it for real. But it seems a bit odd to jump from "world-class" to "never heard of it before."

From a screenshot of LinkedIn: "Mechanical Engineer, IJK Controls, "Reworked existing two-axis gimbal design to fit specifications of new project by redesigning..."

Maybe a mechanical engineer can tell how much skill that requires. I have no idea.
