Victims of a shooting spree are being mourned in Kalamazoo, Mich., where Jason Dalton, the man suspected of killing six people Saturday, is expected to be arraigned Monday. Police have been trying to determine a motive for what seem to be random attacks.

Eerie details have emerged about the case — including a witness’s account of getting an Uber ride from Dalton, 45, who was a driver for the ride-hailing service.
