Police baffled by gunman’s motive for 7-hour rampage in Michigan

A gunman who seemed to choose his victims at random opened fire outside an apartment complex, a car dealership and a restaurant in Michigan, killing at least six people during a rampage that lasted nearly seven hours, police said.

Authorities identified the shooter as 45-year-old Jason Dalton, an Uber driver who police said had no criminal record.

They could not say what motivated him on Saturday night to target victims with no apparent connection to him or to each other.
