FOREST GROVE, Ore. — A rural property outside Portland exploded into one of Oregon's grimmest crime scenes this weekend, after firefighters chasing a car fire stumbled onto the bodies of five people spanning three generations of one family and their closest friends. By Monday, investigators confirmed the accused killer never faced a courtroom: he was found dead of an apparent self-inflicted gunshot wound in his car more than 175 miles away.

Washington County sheriff's deputies were dispatched at 5:27 a.m. Saturday to a reported vehicle fire on Otis Lane, a wooded stretch west of Forest Grove, roughly 25 miles from downtown Portland. Instead of a routine blaze, firefighters found human remains near the burning car, triggering what the sheriff called one of the most tangled death investigations of her career.

By Sunday night, the Washington County Sheriff's Office had identified all five victims: Mary Elizabeth Kimsey, 85; her daughter, Rowan Karla Kimsey, 60, who owned the property; Rowan's daughter, Stella Jade Kimsey, 26; Stella's best friend, Linsey Mae Haraldsen, 26; and Haraldsen's partner, Alvin Raymond Chu, 27. Four dogs and cats also died at the scene, and a fifth animal was later euthanized from its injuries.

The suspect, Benjamin Charles Parker, 36, was Stella Kimsey's boyfriend and lived on the property. Deputies say license-plate-reading cameras helped Enumclaw, Washington police track his vehicle across state lines. He was found dead inside it on Sunday, in what the sheriff's office described as an apparent suicide.

"Quite This Complex"

Sheriff Caprice Massey did not mince words describing the scene to reporters over the weekend.

"I will say that 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."

Investigators say the killings do not appear random — Parker knew everyone at the property — and that there is no continuing danger to the public. A motive has not been released, and the sheriff's Major Crimes Team, working with outside agencies, says the case remains active.

Coverage from Oregon Public Broadcasting describes a tight-knit household: three generations of Kimsey women living together, joined by Stella's closest friend and her partner, in a rural pocket of Washington County known for its small farms and quiet neighbors. Neighbors told reporters the loss has hit the community hard, describing genuine warmth among the group before the killings.

NBC News and ABC News both confirmed the identifications and the cross-state manhunt that ended with Parker's death, citing the sheriff's office as the source for the timeline.

No charges will be filed given the suspect's death, but the sheriff's office says it intends to release further details, including any evidence on motive, as the investigation continues this week. Funeral arrangements for the five victims had not been announced as of Monday evening.
