KALAMAZOO, MI (AP)-- A law enforcement official says investigators haven't found a reason for the southwestern Michigan shooting rampage that left six people dead and two severely wounded.
Kalamazoo County Undersheriff Paul Matyas told The Associated Press Thursday a motive remains elusive five days into the investigation. That includes multiple interviews with Jason Dalton, the man police say admitted to Saturday's Kalamazoo-area slayings and faces murder and attempted murder charges.
Authorities say Dalton ferried passengers as an Uber driver the evening of the attacks. A passenger says he reported Dalton's erratic driving to police shortly before the shootings began, and the recklessness started after he received a phone call.
Matyas says that call doesn't appear to be "any type of trigger mechanism" for the crimes.
Dalton's attorney, Eusebio Solis, has declined to discuss the case. Paul Vlachos, a lawyer representing other members of Dalton's family, tells ABC's "Good Morning America" that Dalton was acting depressed leading up to the shootings but they also know of no motive.
