KALAMAZOO COUNTY, Mich. - A man visiting Kalamazoo, Michigan says he came face-to-face with a suspected gunman accused of killing six people over the weekend.
For almost seven hours, police say, Jason Dalton drove around Kalamazoo County, stopping to shoot people at an apartment complex, a car dealership and restaurant parking lot.
The shootings left six people dead and two others in critical condition.
Between the shootings, Dalton picked up and dropped off passengers for Uber, a source with knowledge of the investigation told CNN.
Derek told WOODTV that he was at a bar with his family Saturday night when someone told him there was a killer on the loose.
He says he called Uber to take him and his family back to their hotel, because he thought it was safer to drive than walk.
When his driver, Jason, showed up, Derek says he cracked a joke.
“I kind of jokingly said to the driver, ‘You’re not the shooter, are you?’ He gave me some sort of a ‘no’ response… shook his head…
“I said, ‘Are you sure?’ And he said, ‘No, I’m not, I’m just tired,'” Derek continued. “And we proceeded to have a pretty normal conversation after that.”
Derek told the local news station that Jason Dalton appeared to be calm and quiet throughout the seven minute trip.
Dalton was arrested 20 minutes after dropping Derek and his family off at their hotel.
Derek told WOODTV that he wasn't sure if their driver was the suspected killer until he saw his picture on the news Sunday morning.
“It was the same guy,” Derek said.
Derek provided WOODTV with a copy of his Uber receipt that shows Dalton was his driver.
One man told WWMT that he had an entirely different experience when he rode in Dalton's vehicle earlier that day.
Matt Mellen said he rode in Dalton’s car shortly before the rampage started.
“We got about a mile from my house, and he got a telephone call,” Mellen told CNN affiliate WWMT.
“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 he called the police. “He was surprisingly calm. I was freaking out.”
Why Dalton may have driven around his own community, gunning people down randomly, remains a mystery.
Dalton might speak for the first time in court Monday afternoon, when he is expected to be arraigned.
