Allen Ivanov, 19, told detectives he bought the semi-automatic rifle a week ago for target practice and had even scheduled a safety class for August, according to a probable cause form released Monday. He got excited, like happy," said Sultan Akbar, a high school friend who last spoke to Ivanov on graduation day in 2015. On Monday, Snohomish County District Court Judge Anthony Howard affirmed a finding of probable cause to hold Ivanov on investigation of one count of aggravated first-degree-murder domestic violence, two counts of first-degree murder and one count of attempted first-degree murder. At a brief court hearing Monday afternoon, he was ordered to be held without bail and to have no contact with the families of the victims. His lawyers expected charges to be Tuesday and say it could be a capital case in which the death penalty could be a punishment option. Killed were Ivanov’s ex-girlfriend, Anna Bui, Jake Long and Jordan Ebner, all 19. Will Kramer, 18, was wounded and was in serious condition Monday in the intensive-care unit at Harborview Medical Center, a hospital spokesman said. “They obviously didn’t see this coming and are grieving along with many others in this community over what happened,” said Tim Leary, who is also representing Ivanov. “I’m shocked … those guys aren’t here anymore.” 
 
 He was friends with Ivanov, who he said seemed to have an explosive temper, once threatening to get Akbar kicked out of school after Akbar reported to a teacher that Ivanov had copied his work. Ivanov’s mother told them Bui “was essentially like a daughter to them,” Wagnild said. The Washington State man accused of killing three people at a party on Friday night with an AR-15 read the rifle's instruction manual just moments before opening fire, court records show. Ivanov became jealous after he said he saw photos of Bui on Snapchat with other young men — evidence “she was getting on with her life without him,” the document says.  EVERETT, Wash. -- Allen Ivanov, the 19-year-old accused in the mass shooting in Mukilteo, said that it was about his "dream girl," court documents say. Ivanov said he became angry when he heard from others that Bui “was seeing other guys while the two of them were talking and that made him angry,” police wrote. The affidavit says Ivanov claimed he purchased the Ruger AR-15 rifle about a week ago, intent on using it for target practice. He told police he viewed “the rifle as a symbol of power,” the affidavit said. Ivanov then returned to his car, where he read the owner’s manual for the rifle, loaded the magazine and inserted it into the AR-15, the affidavit says. He was discovered by a male partygoer, who said, “No, no, no,” before Ivanov opened fire, shooting the male, according to the affidavit. Ivanov told police “it was too late to turn back, and once he had pulled the trigger, his adrenaline kicked in.” He entered the house through a side door, found Bui and shot her twice, it says. and shot her twice, killing her, then gunned down another man running toward the party, the document says. From the master bedroom balcony, he fired at two more people in the driveway, then climbed to the roof and discovered that he'd emptied his rifle. "Ivanov stated that once the magazine was empty, he returned to his car and drove away," the document says. As part of the investigation into the killings, a detective spoke by phone with a person described as a “witness from Kentucky,” who said that two or three days earlier, Ivanov had sent him text messages “regarding committing a mass shooting,” the affidavit says.
– The teenager accused of killing three people at a house party near Seattle bought his AR-15-style rifle so recently he had to study the instruction manual before the rampage, police say. According to court documents, 19-year-old Allen Ivanov has told police that he bought the Ruger firearm just a week ago and carried out the shooting because he was angry that the "dream girl" he split up with two months ago didn't want to get back together with him, NBC News reports. Investigators say Ivanov has told them that on Friday night, he bought another magazine for the gun after leaving his job at an Apple Store early. He drove to the party in the suburb of Mukilteo around 10pm and looked through a window. After spotting his ex with another man, he returned to the car to study the rifle's instructions. Around midnight, he allegedly returned to the party and opened fire. Cops say Ivanov killed his ex-girlfriend, Anna Bui, as well as partygoers Jake Long and Jordan Ebner, all 19 years old. An 18-year-old victim was seriously injured. Ivanov, who fled after the shooting and was arrested more than 100 miles away, is being held without bail on charges including first-degree murder, KOMO reports. Investigators say the teen's recent posts on social media suggest the murders were planned. Tim Leary, a lawyer hired by his parents, tells the Seattle Times it worries him that Ivanov could buy the AR-15 when he is too young to buy beer. The fact that he had to read the manual "speaks volumes to his youth and inexperience and highlights the lethality of the weapon involved," he says. (The family of the AR-15's inventor says he'd be "sickened" by his gun's use.)
