In a twist of fate, Bruce Lindahl severed his own femoral artery during the attack, and he bled to death at the scene, dying while committing the murder.
And then there's the fact that even though he's severed the femoral artery in his left leg, he hasn't bled out, when he could have done within just five minutes.
Judging from the entry and exit wounds, as well as the amount of hemorrhaging, the bullet most likely clipped the femoral artery, one of the largest blood vessels in the body.
But to hear him actually sever his own femoral artery, I don't know if I've ever heard that before, but it's certainly common, as you said, for them to at least be injured.
So now my, I don't do this myself, but my colleagues, some of whom are neurosurgeons, some are interventional radiologists, they can go through the groin in the femoral artery or through the radial artery.
