The Washington County Sheriff's Office has identified all five people killed at a rural property near Forest Grove and confirmed that the suspect, 36-year-old Benjamin Charles Parker, was found dead of a self-inflicted gunshot wound in Washington state.

Tigard Police Department and Tualatin Valley Fire & Rescue both assisted the investigation through the Washington County Major Crimes Team, a multi-agency unit that responded after fire crews discovered human remains at 47350 NW Otis Lane on Saturday, Aug. 22.

The victims are Mary Elizabeth Kimsey, 85, of Portland; Rowan Karla Kimsey, 60, of Forest Grove; Stella Jade Kimsey, 26, of Forest Grove; Linsey Mae Haraldsen, 26, of Portland; and Alvin Raymond Chu, 27, of Portland.

Three generations of one family

Three generations of the Kimsey family were among the dead. Mary was Rowan's mother and Stella's grandmother. Rowan, described by her family as a talented traditional and tattoo artist, owned and lived at the 14-acre property, which included a main house, a cabin and livestock including sheep, chickens and goats. Stella also lived there with Parker, her boyfriend of about a year. The family described Stella as fiercely passionate.

Haraldsen was Stella's best friend. Chu was Haraldsen's partner. Both had driven separately to the property to check on the Kimseys before they were killed.

Stella's sister Alexis asked the public to show compassion and respect to the Parker family as they navigate their own grief, according to KPTV.

How it unfolded

At a Tuesday, Aug. 25, press conference, lead detective Mark Povolny laid out the sequence of killings for the first time, according to OregonLive.

Investigators believe the killings occurred Friday, Aug. 21, after a major fight between Stella Kimsey and Parker either Thursday night or early Friday morning. Stella told Parker to leave.

On Friday afternoon, Stella was on the phone with Haraldsen when the call suddenly dropped. Unable to reach Stella, Haraldsen called Rowan, who went to check on her daughter. At 8:30 p.m. Friday, Mary Kimsey texted a friend saying she could not reach anyone and was heading to the property with Chu.

"We believe Mr. Parker murdered Stella first," Povolny said. "We believe he then murdered Rowan as she came to check on her daughter. When Lindsey drove out to the property from her home to check on Rowan and Stella, he then murdered her. Finally, Mary and Alvin arrived, and he murdered both of them."

All five were shot with a .22-caliber firearm. Parker also fatally shot two dogs and two cats; a third cat was later euthanized due to injuries. Livestock have since been rehomed. Parker set fires at each of the bodies and attempted to set Stella's car on fire before fleeing in a silver Toyota Tacoma registered to Rowan Kimsey.

Confession and death

Cell phone data showed Parker's phone left the property at approximately 4:42 a.m. Saturday and was shut off at 5:15 a.m. after moving through Forest Grove and Cornelius. It was turned back on at 7:55 p.m. near Enumclaw, Washington, about 50 miles southwest of Seattle.

Parker called his mother at 7:55 p.m. and confessed, telling her the attack was premeditated and that he had planned to kill three people but ended up killing five, according to OregonLive's reporting on the press conference. He did not disclose a motive.

Parker's mother contacted detectives Sunday. Enumclaw police located the Tacoma behind a Safeway grocery store using a Flock license plate reader system. Parker was found dead inside.

Multi-agency investigation

The scope of the response reflects the severity of the case. Beyond the Washington County Major Crimes Team, the Portland Police Bureau, Washington State Police, Enumclaw Police Department, Kingston (Rhode Island) Police Department, Upper Merion (Pennsylvania) Police Department and the FBI all assisted, according to the Sheriff's Office.

Sheriff Caprice Massey said Sunday, Aug. 23, that the scene was unlike anything in her tenure. "In my 22 years here, I have not been a part of or witnessed a scene quite this complex involving this type of an investigation," Massey said, according to Valley Times.

The Sheriff's Office said it does not believe there is any danger to the public and that the killings were not a random act of violence. Evidence processing and laboratory analysis are expected to take months.

Anyone with information is asked to call Washington County non-emergency dispatch at 503-629-0111 and reference case number 50-26-11866.
