Ivanov bought gun 4 days before shootings, mother tells police

MUKILTEO — Allen Ivanov’s mother told police that her son had purchased a semiautomatic rifle just four days before he allegedly killed three people and wounded another at a Mukilteo house party.

Investigators have seized Ivanov’s computer and searched his home for potential evidence in the ongoing investigation into the July 30 shootings, according to a new search warrant filed Monday in Snohomish County courts.

Detectives in part were looking for additional firearms and ammunition but apparently did not find any at the home, the documents show.

Ivanov remains in jail, charged with aggravated murder and attempted murder. He is accused of killing his ex-girlfriend, Anna Bui, and friends, Jordan Ebner and Jake Long, all of whom were 19.

Will Kramer, 18, also was shot. He was listed Monday in satisfactory condition at Harborview Medical Center in Seattle. “He continues to heal and recover,” a hospital spokeswoman said.

Ivanov, 19, was living with his parents in Mukilteo after his freshman year of college. He and the victims all had attended Kamiak High School. He told detectives that he and Bui had broken up two months before the shootings, and that he became angry and jealous when his plan for reconciliation didn’t work out the way he wanted.

Within hours of the shootings, detectives obtained a judge’s permission to search the Ivanov family home.

Ivanov’s mother reportedly had told them her son bought the rifle, a Ruger model similar to the AR-15, at Cabela’s in Tulalip. He returned to the store on July 29 to buy a second 30-round magazine.

Ivanov’s father said he believed his son purchased the weapon “for self defense, because he was afraid at home,” the search warrant says. The documents made public so far do not provide any other context for that statement.

Detectives wrote that they hoped to access Ivanov’s social media accounts through the computer. He reportedly posted on Twitter and other social media about the weapon.

Memorial services for Bui and Long were held last week. Ebner’s memorial is set for Monday.

A community forum on dealing with grief and loss is scheduled from 6 to 8 p.m. Thursday at the Rosehill Community Center, 304 Lincoln Ave., Mukilteo.
