Uber driver Jason Dalton reportedly told a passenger that he was “just tired” when the man jokingly asked whether he was the shooter who had gone on a rampage in Kalamazoo, Michigan over the weekend.

Dalton allegedly drove around the city on a shooting rampage on Saturday evening, killing six people. When news of the murders reached a man in the backseat of an Uber car, he tried to lighten the mood. He didn’t get the reaction he was expecting.

The man, who gives his name as Derek, said Dalton was calm when he picked him up.

“I jokingly said to the driver, ‘You aren’t the shooter, are you?’ and he either shook his head or said no, and I said, ‘Are you sure?’ And his response wasn’t like you would expect, like a laugh. It was just very calm and quiet. It was, ‘I’m just tired. No, I’m just tired,'” Derek said.

Unbeknownst to Derek, there was already a manhunt underway for a car fitting the description of Dalton’s vehicle. He escaped unharmed, and about thirty minutes later, Dalton was arrested. He is scheduled for arraignment today, but people across the country are anxious to know whether there was a motive for the killings, which took the lives of six innocent people in various locations.

One woman was shot when Dalton opened fire near an apartment complex because she shielded children from the gunfire. She is listed in serious condition today.

“This person put themselves between the children and the shooter, right away,” Sheriff Richard Fuller said, referring to her as a “hero”.

A 14-year old girl was also seriously wounded in the attacks and is in critical condition.

Derek wasn’t the only fare Dalton picked up during the nearly seven-hour spree; passenger Matt Mellen says he got scared when the Uber driver began driving erratically and jumped out of the car the first chance he got.

“We got about a mile from my house, and he got a telephone call. After that call, he started driving erratically, running stop signs. We were kind of driving through medians, driving through the lawn speeding along and then finally, once he came to a stop, I jumped out of the car and ran away,” Mellen said.

Mellen also said that Dalton was oddly calm throughout the ordeal; he reportedly surrendered peacefully to police.
