The initial 4chan post first appeared on Tuesday at 2:56pm EST. According to NBC, an affidavit written by deputies in the sheriff's department of Kitsap County states that the crime scene 'matched the deceased female, trauma we observed, and the residence interior' visible in the photos posted to 4chan. A man arrested Wednesday night for the alleged murder of 30-year-old Amber Coplin in Port Orchard, Washington may have documented the act on a 4chan thread.
