Seattle, Jul 31: A gunman attacked a gathering of young adults at a suburban Seattle home on Saturday, July 30, killing two people at a fire pit before firing more shots from the roof, the grandmother of one of the witnesses said.
Three people were killed and another injured at the Mukilteo property. State troopers pulled over and arrested the fleeing suspect on an interstate three counties away, authorities said.
"She was hiding in the closet and called me from the closet while it was going on," Susan Gemmer said of her 18-year-old granddaughter, Alexis.
"We were texting back and forth, telling her to stay quiet, stay calm, we're on our way. She kept saying, 'They're dead, they're dead, I saw them, I was right there and I saw them.'"
Gemmer said that according to her granddaughter, the gunman arrived with a rifle at the party of about 15 to 20 friends from Kamiak High School â mostly recent graduates aged 18 to 20.
The gunman walked through the house to the fire pit out back, where he shot two of the victims. Those present knew the gunman, she said, and he and one of the victims had broken up last week.
The shooter then made his way onto the roof, where some of the friends were hanging out, Gemmer said.
The young man who lived at the home tried to lead Alexis Gemmer to safety by escaping out the garage. As they rolled under the garage door and the boy bolted across the street, the gunman began shooting at him from the roof, her granddaughter told Gemmer.
"She panicked and ran back in the house and hid in the closet until police arrived," Gemmer said. Authorities did not immediately release information about or the identities of the suspect or the victims.
"Our community has suffered a great loss tonight," Mukilteo Mayor Jennifer Gregerson said.
"There were many young people who saw and heard things that no one should ever experience."
The shooting happened in the upscale Chennault neighborhood of Mukilteo, a waterfront town of about 20,000 people, 25 miles north of Seattle. Washington State Patrol Trooper Will Finn said the male suspect was pulled over at around 2 a.m. heading south on Interstate 5 near Chehalis, about 113 miles away.
Finn declined to release information about his identity, but said troopers returned him and the vehicle he was driving to the custody of Mukilteo police. Authorities said they planned to release more information Saturday afternoon.
