Michigan Uber driver killer says the 'devil' app controlled his mind and body ...

The disturbed former Uber driver who pleaded guilty to killing six people in a shooting rampage in 2016 says the 'devil' app possessed him and told him to commit the bloody murders. 

Michigan Uber driver Jason Dalton, 48, pleaded guilty to the February 20, 2016 murders last month, nearly three years after the attacks took place, and was sentenced to life in prison. 

In chilling never-before-seen interrogation tapes an emotionless Dalton reveals how the app guided him to kill.   

'The minute that I logged on, to be honest with you, I don't know what happened. I know you guys are going to have a hard time believing this but it literally took over (my) mind and body,' he told investigators in the tapes obtained by ABC's 20/20.

He had been working for Uber for less than a week when he noticed a symbol of the eastern Star after logging into the app. When he clicked on it, he claims the image of the devil appeared. 

'I just tapped it and then there was like a devil head that popped up,' Dalton said. 'It was some sort of like horned, horned head like a cow head or something...I pressed that button and that's where all the problems went after that.'  

The app would start off red then switch to block. 

'When it's in that black mode, it literally has control of you. It  would do a little blink at me,' he said. 

Dalton claimed the Uber app gave him an assignment that he had no choice but to complete.  

The phone communicated with him, responding 'yes' to his questions with one beep and 'no' by two beeps.
