A teenager accused of killing three people in a mass shooting at a house party reportedly texted about his intentions before the attack.
Allen Christopher Ivanov, 19, is accused of killing Anna Bui, Jake Long and Jordan Ebner. The shooting, which occurred in a Washington town near Seattle, also left Will Kramer, 18, in serious condition, according to the Los Angeles Times.
Ivanov is reported to have purchased an AR-15 semiautomatic rifle about a week before the shooting. He said that he'd intended to use it for target practice, and had signed up for a gun safety course, according to KCPQ. Police said he told them he saw the gun as a "symbol of power."
Bui was Ivanov's ex-girlfriend. He had reportedly broken up with Bui two months earlier after around a year and half of dating. He said that after they broke up, Bui posted images of herself on Snapchat drinking with other young men. Ivanov reportedly found the Snapchats "hurtful," and began to regret breaking up with Bui.
The two started talking again and Ivanov thought they might get back together, but he became angry when he found out that Bui, who Ivanov had described as his "dream girl," was still dating other people.
A few days before the shooting, Ivanov reportedly texted a friend saying he was considering committing a mass shooting. In the days leading up to the attack, Ivanov posted on various social media, including a photo of the AR-15 on Instagram, as well as a tweet reading "First and last Tweet. I've been through it all," on Twitter.
The teenager then drove to the house party on July 29, after leaving work early and buying a magazine for his rifle, which he said he needed for class. Ivanov then entered the party, and became incensed when he saw Bui with another young man. He then reportedly went back out to his car and read the AR-15's instruction manual before loading the rifle and coming back into the house and shooting at a crowd of around 20 teens.
Police said Ivanov confessed to the murders the next morning, and waived his right to an attorney.
"Our community has suffered a great loss tonight," Mukilteo Mayor Jennifer Gregerson said after the shooting. "There were many young people who saw and heard things that no one should ever experience."
