Allen Christopher Ivanov of Mukilteo, Washington was arrested after killing three teenagers at a party on July 30, 2016. It is said that Ivanov had just had a break up with one of the victims, Anna Bui. Ivanov went and posted on Twitter shortly carrying out the shooting. He seems to have hinted at his plans on Instagram as well. Ivanov had posted a picture of his new assault rifle days prior with three bullets next to it. He captioned it “You can’t run with me :(” Some sources say he purchased an assault rifle weeks before the murders, others say just a week prior. Sources are making it seem as if the shooting wasn’t premeditated. That after coming to a party where he saw his ex-girlfriend with another guy, Ivanov went to his car in a jealous rage and got his assault rifle. Not knowing how to use it, he apparently read the manual before loading the magazine. It’s also being reported that Ivanov reached out to a friend in Kentucky days prior warning them there would be a mass shooting. Investigators have seen these text messages. Ivanov claimed that he crept around the side of the house to hide and was seen by one of the male victims. The man allegedly said “no” over and over. Ivanov did not spare him. He then went into the house and shot his ex-girlfriend Anna Bui twice. He then shot another male. Going onto the balcony of the master bedroom, he shot at two more males. He sped away from the scene of the crime and was arrested about 100 miles away after being stopped for speeding. The three murdered were identified as Anna Bui, Jordan Ebner, and Jake Long. All three victims were 19. One more male was injured. Ivanov, a fluent Russian speaker, told investigators Anna Bui was the first girl he had ever kissed. He worked at the Apple Store in the Genius Bar and graduated High School in 2015. He was sentenced to life in prison on January 12, 2017.
