The Latest: Documents: Shooter read gun manual before attack
{{#rendered}} {{/rendered}}The Latest on a shooting at a small party in Mukilteo, Washington, that left three people dead and one injured early Saturday (all times local):
10:55 a.m.
Court documents say a 19-year-old man who shot and killed three people at a party in Washington state was so unfamiliar with his newly purchased AR-15 semi-automatic rifle that he parked his car across the street from the party and read the firearm's instruction manual just before the attack.
{{#rendered}} {{/rendered}}Authorities say Allen C. Ivanov was arrested by state troopers on Interstate 5 about 100 miles from the bloody scene he left in Mukilteo, a well-off Seattle suburb. In a probable cause statement released Monday, they say he confessed to the killings and that he did it because he was angry that his ex-girlfriend seemed to be moving on with her life after their recent break-up. She was one of the victims.
The document also says Ivanov had texted someone in Tennessee about his plans a couple of days before the shooting. It's unclear whether the recipient of those texts tried to report them to anyone.

A 19-year-old man suspected of fatally shooting three people at a party in a Seattle suburb over the weekend is expected in court Monday afternoon.
Allen Ivanov is being held in the Snohomish County Jail.
{{#rendered}} {{/rendered}}The Snohomish County Medical Examiner's Office has identified the three 19-year-olds who were killed at the party early Saturday in Mukilteo as Jordan Ebner, of Lake Stevens; Jacob Long, of Everett; and Anna Bui, of Everett. They died of gunshot wounds. A fourth person was also seriously injured.
Hundreds attended a vigil Sunday at a local church to remember the victims. The Daily Herald of Everett reports they were recent graduates of Kamiak High School in Mukilteo, a waterfront city of 21,000 north of Seattle.
Both Bui and Ivanov were students at the University of Washington.
