Portland Mayor Charlie Hales released a statement regarding the shootings. It reads:

“My heart is with all of the families that have lost loved ones as we continue to experience a year of unprecedented violence here in Portland; gun violence is taking a terrible toll on our community. A gun violence crisis has been growing nationally and here in Portland. More than 800 ammunition cases have been recovered in 135 gang-related shootings alone, with domestic violence and other incidents adding to that grim tally.

“We all have a part to play in saying, ‘no’ to more violence: Join ‘Enough is Enough’ and the Community Peace Collaborative; alert the police when you see violence; and most importantly, support our brave law enforcement officers as they work day and night to prevent more gun violence from ripping apart our community.”KOIN’s Kohr Harlan contributed to this report.
