This guy supposedly murdered his passenger with a gun while driving his Tesla. How is such a thing possible? He is also a Cornhole champion, so there has to be some video of this guy out there doing things
Your link is wrong. Whatever it’s supposed to be, it ain’t. It looks like a broken link to this thread, which is obviously not useful in providing context in your otherwise completely context-free question.
Here’s a link about the murder

Here’s the link I had posted in the other thread
The guy’s like a real-life Anakin Skywalker. I don’t know whether to be horrified or really impressed…
[After the shooting] He then pulled over and asked two backseat passengers to help pull Wells out of the car.
Oh, wow, it’s days like that you find out who your friends really are.
Alas, they refused. But still:
Webber then fled the scene with Wells still in the car. Wells’ body was then found in a yard on Newport Church Road in Charlotte Hall, MD. Wells was pronounced dead at the scene. […] Police have not explained how Webber, a quadruple amputee, was able to drive a car or fire a weapon.
Never let anyone tell you what you can or can’t do.
What did he do, drag the body out with his teeth?!
Here’s a supposed video of him loading, cocking, and shooting a handgun:
I desperately want to make a joke about handguns, but this is FQ and we don’t even have informed speculation yet, let alone answers. 
FTR, here’s the start of the discussion in the other thread which originally cited the news of this interesting fellow:
This is probably the cite the OP wanted in their post.
The prosecutors are probably going to be pretty grateful for that video.
That certainly answers half of the OP’s question, I’d say. It’s unfortunate that he wasn’t driving his Tesla also in that video.
Sorry for the broken link, thanks for the followup information. I must say I am quite impressed by what this guy can achieve.
I assume his Tesla is mostly driven by the cars guidance system and that he also uses his arm stubs to steer when neccesary. Wow.
I also wonder what the guy could have said or done to piss this guy off to the point of killing him. I mean obviously the man has been insulted and faced countless obstacles in his life. Maybe the guy called him bob one too many times. 
OK. Enough of the jokes. I don’t want this turning into a tasteless joke spin.
One of those sick Bob jokes from a few decades ago.
