Boulder PD: Still no motive in supermarket massacre

Investigators so far have spent more than 3,000 total hours conducting 156 interviews and gathering more than 223 leads to unravel what might have motivated the suspect, 21-year-old Ahmad Alissa, to travel from Arvada to Boulder to open fire on shoppers and workers in the middle of a Monday afternoon.

“Like the rest of the community, we too want to know why. Why that King Soopers, why Boulder, why Monday?” Boulder Police Chief Maris Herold said at a news conference Friday morning. “Unfortunately, at this time, we still don’t have those answers.”
