On July 5, 2015, 29-year-old Sara Arthur was shot while in Les Gove Park in Auburn, Washington. She and a companion, 32-year-old Chaz Schmitz, had been in the park after traveling from Idaho and finding work at local fireworks stands. An argument between Schmitz and 39-year-old Charles Clayton Petrich escalated; Petrich is reported to have retrieved a .22 caliber rifle from his pickup and opened fire. Schmitz died at the scene; Arthur was taken to Harborview Medical Center and died the following day.

Petrich fled the park but was located and arrested at a 7-Eleven in Auburn less than 24 hours later. Authorities charged him in King County with two counts of second-degree murder and one count of unlawful possession of a firearm; bail was set at $4 million. He pleaded not guilty in late July 2015.

Are there readers who knew Sara, Chaz, or who were in the Les Gove Park area that evening and can share information?
