4chan is an anonymous image posting site, its mostly filled with people wanting to "shitpost" and say things they normally wouldn't say in real life or post on facebook or anything associated with their real name.
The most notorious image board on 4chan is /b, which is the random board. Basically there is no central topic anything goes.
On the 4th of November 2014, an anonymous user made a post on the /b board of 4chan that started with"Turns out its way harder to strangle someone to death than it looks on the movies" with that he posted a picture of a dead women. At first the people who seen the post figured it wasn't real. But he followed up with another picture and wrote "She fought so damn hard"
This was really disturbing because he was posting on the /b random board while he was still at the murder scene.
His last update on the thread that he posted was "Check the news for port orchard Washington in a few hours. Her son will be home from school soon. He'll find her, then call the cops. I just wanted to share the pics before they find me. I bought a bb gun that looks realistic enough. When they come. i'll pull it and it will be suicide by cop. I understand the doubts. Just check the fucking news. I have to lose my phone now"
Check the date of the news release, its the same date the user started the thread on the /b random board

A twitter user posted this tweet a day later
