EVERETT, Wash. — A 19-year-old man who shot and killed three people Saturday at a party in suburban Seattle was so unfamiliar with his newly purchased AR-15 semi-automatic rifle that he parked his car across the street and read the firearm's instruction manual just before the attack, police wrote in a probable-cause statement made public Monday.
Allen C. Ivanov was arrested by state troopers on Interstate 5 more than 100 miles from the bloody scene in Mukilteo, a north Seattle suburb, authorities said.
Ivanov was formally charged with the murders on Tuesday afternoon.
Prosecutors filed three charges of aggravated first-degree murder against Ivanov. He also faces one charge of attempted murder, alleging that he shot and seriously injured an 18-year-old man, and one of first-degree assault.
A letter from Ivanov, the suspect in a Mukilteo triple fatal shooting, was received Monday from a source by KIRO 7 reporter Joanna Small. The letter from Ivanov addresses a list of his family members and loved ones.
“Nobody on this list is to be accused, searched, or questioned. They had nothing to do with anything,” the letter from Ivanov begins. “I wish I was everything you wanted.”
"I'll see you in the next life," the letter ends. [Read the entire letter from Allen Ivanov here.]

Probable-cause statement release new, chilling information
Authorities said he confessed to the killings and that he did it because he was angry that his ex-girlfriend, Anna Bui, seemed to be moving on with her life after their recent breakup. She was one of the victims.
The document also indicates that Ivanov gave a few indications of his troubling intent: He texted someone last week in Tennessee "regarding committing a mass shooting"; he posted on Twitter, "What's Ruger gonna think" — an apparent reference to the manufacturer of his rifle; and that he told his supervisor at an electronics store on Friday that the previous night he had put the rifle in the trunk of his car and gone to a quiet spot and just sat.
Ivanov had bought the assault-style weapon about a week before the attack, saying he planned to use it for target practice and that he had signed up for a gun-safety class this month, Mukilteo Police Detective John Ernst wrote in the probable-cause statement.
"Ivanov stated that he showed up to the homicide scene at approximately 2200 hours, and parked across the street and watched," Ernst wrote. "He said that he creeped up toward the house and saw A with another male and got angry. He said that he returned to his car, read the instruction manual for the rifle, loaded the magazine, placed the magazine in the rifle, and sent the rifle's selector switch to 'safe.' He then returned to the victim house property."
Ivanov told detectives he crept around the back of the house and hid near the living room windows, where he was eventually discovered by one of the young men attending the party.
"The male said, 'No, no no,'" Ernst wrote. "Ivanov stated that he was 'scared,' he flipped the selector switch to fire and shot the male. He stated that at that point it was too late to turn back, and once he had pulled the trigger his adrenaline kicked in."
Ivanov said he entered the house through a side door, found Bui and shot her twice, then continued through the house, saw through the front door another man running toward the house and shot him, according to the probable-cause statement. From a balcony off the master bedroom, he said, he shot at two more men in the driveway before going onto the roof, realizing his magazine was empty and fleeing.
Hundreds remember 3 slain victims
At the vigil, it was clear that friends and family members are still in shock over what happened in the affluent Chennault neighborhood.
In addition to Bui, of Everett, Jordan Ebner, of Lake Stevens, and Jacob Long, of Everett, were killed. They were all 19 and recent graduates of Kamiak High School in Mukilteo, a waterfront city of 21,000 people.
A fourth person, 18-year-old Will Kramer, was wounded and remained in serious condition Monday at Harborview Medical Center in Seattle.
Bui and Ivanov were students at the University of Washington. A vigil was held on Monday afternoon.
