Ali then , apparently, went berserk. He carjacked a retired old man, executing him on sight, and shot and killed 2 other motorists, carjacking and injuring people with his "twelve gage shotgun" for about four hours, until finally, police caught up with him.
And what did this "Ali" do? Well, like the madman Chris Dorner , Ali shot and killed himself.
The man has not had a criminal record, but appears to be an abuser or user of drugs. Perhaps he took some drugs, bludgeoned a woman to death, ran out, took a car, took more drugs (probably bath salts) , and killed some people, then killing himself in anger and fear?
God damnit, we don't understand anything anymore -_-
