Information reported on komonews.com stated that two groups, which included more than 40 individuals, were picnicking at the park when a verbal argument escalated to a gun fight.

The two men who were killed are reported to be a 33-year-old from Kent and a 30-year-old from Seattle. Three of the injured were taken to Harborview Medical Center in Seattle, and a fourth person was transported to Overlake Hospital in Bellevue.
