"Turns out, it's way harder to strangle someone to death than it looks on the movies."

David Michael Kalac, a.k.a. "The 4chan Killer", is an American murderer who killed his girlfriend and posted pictures of her body on the (in)famous imageboard website, 4chan.

History Edit

Before murdering his girlfriend, Kalac already had problems with the police, being arrested several times for domestic violence and aggravated assault. On November 4, 2014, Kalac visited a bar and drank beer and vodka for four hours. For unspecified reasons, he killed his girlfriend, Amber Coplin, after returning home. Afterwards, he posted photos of her nude body online. Her body was found one hour later by her thirteen-year-old son. Using Coplin's car to escape, Kalac fled from his house and called 911. Investigators were able to trace his cellphone, which resulted in Kalac messaging two of his friends, saying that they would see him in the news. Nineteen hours later, Coplin's car was spotted and police officers pursued the car. However, Kalac managed to escape them by swerving into oncoming traffic.

Hours later, about 20 miles southwest of Portland, Kalac surrendered and was arrested without resistance. He was subsequently convicted of second-degree murder, which was later elevated to first-degree murder. Inside Coplin's bedroom, police found messages written by Kalac, such as "she killed me first" on a picture and "dead" on a driving license, which was left near her head. Kalac's motive for killing Coplin is currently unknown, though he mentioned the fact that he was intoxicated when it happened, and alleged that she had made him angry. Other sources say that Coplin had a romantic relationship with another man, and that Kalac found out about it, resulting in him killing her.

Modus Operandi Edit

"I just wanted to share the pics before they find me."

When killing Coplin, Kalac manually strangled her, then switched to ligature strangulation with a shoelace. While strangling her, he also bludgeoned her in the head with an unspecified object. Afterwards, Kalac removed her clothing and took pictures of her nude body before posting them online with various taunting messages as captions.

Known Victims Edit


Amber Lynn Coplin

"I killed Amber Coplin. I strangled her with my hands, then a shoelace. I had no reason other than I was drunk and she pissed me off. Running from the cops was so fun."

  • November 4, 2014: Amber Lynn Coplin, 30 (manually strangled, then fatally bludgeoned with an unspecified object and strangled with a shoelace)

On Criminal Minds Edit

Kalac's act of posting images of his girlfriend after killing her, accompanied with taunting messages, seems to be almost identical to serial killer William Pratt's signature. William appeared in the episode Hashtag, which aired a week after the murder occurred; the similarities between Kalac's killing and the murders depicted in the episode are most likely coincidental.
