The young man suspected of opening fire at a Mukilteo house party early Saturday morning and killing three people remains jailed without bail.

Allen Ivanov, 19, is suspected of murder after four teens were shot and three died -- including his ex-girlfriend -- at a house party. He is jailed on suspicion of two counts of first-degree murder and one count aggravated first-degree murder.

The dead were identified as former Kamiak High School classmates Anna Bui, Jake Long and Jordan Ebner. Bui and Ivanov are believed to have dated, and police describe her killing as a crime of domestic violence. A fourth young person, Will Kramer, was injured and remains hospitalized at Harborview Medical Center in Seattle.

A high school friend of his who attended Monday afternoon's bail hearing described him as having an "explosive" temper. After his arrest, Ivanov is alleged to have told police he went on the rampage over his ex-girlfriend, whom he described as his "dream girl."

Because Ivanov is suspected of aggravated murder, a Snohomish County District Court judge ordered him held without bail. Ivanov appeared via video at a Monday afternoon court hearing.

After the hearing, a high school friend of Ivanov's, Sultan Akbar, described Ivanov as a "control freak" with an "explosive" temper. He recalled Bui was "extremely nice."

Akbar, 18, came to the hearing with a few other former high school classmates. The group graduated last year.

He recalled sharing several classes with Ivanov and inviting him over to his house. He had an English class with Long, Bui and Ivanov, and knew Ebner in sixth grade.

"I'm feeling shocked at what happened," Akbar said. "I just feel shook up."

Mukilteo police were called to reports of a "mass shooting" in the 10000 block of 64th Place West about 12:30 a.m. Saturday. Witnesses identified Ivanov as the gunman and reported he left the scene in a car.

Investigators searched Ivanov's Twitter account, which included messages from July 28 reading, "What's Ruger gonna think" and "First and last tweet. I've been through it all."

Police reports indicate that Ivanov showed up at the party armed with a rifle shortly after midnight. About 20 people were at the home when the shooting began.

Witnesses reported hearing loud bangs and seeing Ivanov on a balcony pointing his rifle at people.

A state trooper tracked down Ivanov driving on Interstate 5 near Chehalis about two hours after the shooting.

Ivanov agreed to be interviewed by police and said that he committed the shootings in a jealous rage over Bui. He said they dated for 1 1/2 years before he broke up with her two months ago.

He told detectives he was angry about photos Bui had posted on Snapchat with other guys.

Ivanov went on to say he grew jealous and wanted to get back together with Bui, so they started spending time together again in the previous week, police reports indicate. However, he heard rumors that she was seeing other people, which made him angry.

Investigators claim Ivanov said he bought a Ruger AR-15-style semi-automatic rifle about a week before to shoot targets. He bought a second magazine for the gun on Friday. He admitted the gun was a symbol of power to him.

He is alleged to have said she drove to the Friday night party about 10 p.m., parked across the street from the party and "watched." He later approached the house and found Bui hanging out with another guy. He then returned to his truck, read the instruction manual for the rifle and loaded it, incident reports say.

He approached the house and found a hiding spot, but was discovered by a partygoer, who said, "No, no. no." Ivanov told detectives he was "scared," so he shot the man.

Ivanov then reportedly entered the house and found Bui, shooting her twice. He continued through the house and saw another man running toward the house and shot him. Finally, he headed upstairs to a balcony and fired at two more men in the driveway.

He then allegedly ascended to the roof, where he discovered his magazine was empty. He headed back to his truck and drove away.

Someone from Kentucky spoke to Mukilteo police on the phone and reported Ivanov had sent him text messages about committing a mass shooting two or three days earlier.

Snohomish County prosecutors have not yet filed charges in the matter.
