But things turned weird when the passenger confronted him. Dalton reacted with complete calm, denying that he had done anything out of the ordinary. After the passenger managed to escape, Dalton drove to his house to swap cars. And get his gun.
Over the next few hours, Dalton drove around shooting random bystanders and then driving off to pick up passengers. Those who rode with him later said that he was totally normal, chatting with them and sometimes even singing along with the radio. In one case, he shot a woman only after she confirmed that she was not the person he was supposed to pick up. Such was his devotion(?) to his clients. By the time the cops found him, the pendulum had swung back to "strangely calm," and he didn't resist arrest.
When asked why he did all this, Dalton explained that the symbol on his Uber app had changed to that of the Eastern Star (a masonic group his grandmother belonged to). Dalton further claimed that the red driver's icon on his app kept turning black and Devil-like, causing the app to take over his body and make him kill people. He was later deemed competent to stand trial. Hopefully Uber has gotten around to fixing that whole "satanic possession" bug by now.
