Dalton was arrested around 12:40 AM in Kalamazoo during a traffic stop after a local police officer recognized his car. One semi-automatic gun was found in his vehicle. He did not resist arrest and is now in custody. All of the shootings are believed to have been completely random.
One Uber passenger picked up by Dalton appears to have posted a complaint to Facebook accusing him of erratic driving on the day of the shootings. The passenger reported, "911 was called, but surprisingly they didn't seem all that concerned." Police are investigating the report.
According to WOOD, Uber is working with authorities. "We are reaching out to the police to help with their investigation in any way that we can," Uber Chief Security Officer Joe Sullivan said in a statement. Dalton had previously passed a background check, and he appears to have had no prior criminal record.
