THE suspect in a horror Oregon quintuple homicide allegedly targeted his own girlfriend and members of her family and friendship circle, cops have revealed.

Investigators say Benjamin Parker, 36, had been planning a killing spree “for a while” before five people and several pets were brutally gunned down at a secluded rural property.

Parker allegedly shot his girlfriend Stella Kimsey, 26, multiple times alongside her mother Rowan Kimsey, 60, and grandmother Mary Kimsey, 85, according to the Washington County Sheriff’s Office.

Stella’s best friend Linsey Haraldsen, 26, and Haraldsen’s partner Alvin Chu, 27, were also allegedly murdered at the property near Forest Grove on Saturday morning.

Firefighters were initially called to reports of a vehicle fire at the heavily-vegetated property on Northwest Otis Lane shortly after 5am Saturday.

Crews instead discovered what appeared to be bodies and backed away from the scene as sheriff’s deputies raced to the property.

Cops ultimately discovered all five victims and launched a huge murder probe involving detectives, forensic experts, K9 teams and the Oregon State Police Crime Lab.

Detectives have since revealed chilling new details as they pieced together what allegedly unfolded before firefighters stumbled across the bloodbath.

Parker allegedly tried to start fires around each of the five bodies as well as at the home following the killings, Det. Mark Povolny said.

Two dogs and two cats were also found shot dead.

A third cat suffered a gunshot wound and was later humanely euthanized, cops said.

Parker allegedly fled Oregon following the massacre before he was discovered dead inside his car in Enumclaw, Washington.

Officials believe he died from a self-inflicted gunshot wound.

But investigators have now revealed Parker allegedly made a disturbing confession to his mother before his death.

Povolny said Parker called her on Saturday night and admitted carrying out the killings.

“He said he had been planning this for awhile,” Povolny said.

“He said he planned to kill three people, but two more people were also killed.”

Investigators have not revealed which three people Parker allegedly intended to murder.

Parker also did not tell his mother what allegedly drove him to carry out the attack, according to cops.

But detectives have uncovered evidence of an apparent explosive row between Parker and Stella just hours before the bloodshed.

Mary reportedly texted a friend on Friday night saying her granddaughter and Parker had become embroiled in a “horrible fight.”

She said “Stella told him he had to leave,” according to Povolny.

A disturbing chain of events then allegedly unfolded as Stella’s loved ones desperately tried to find out what was happening.

Linsey had reportedly been speaking to Stella on the phone around the time of the argument when their call suddenly cut out.

She contacted Stella’s mom Rowan, who said she would head to the property to check on her daughter and call back, cops said.

But Rowan reportedly never called back, prompting Linsey to also head to the property.

Mary later became alarmed when she could not reach any of the three women and planned to pick up Alvin and travel there herself, investigators said.

All five would ultimately be found dead.

“Although the suspect is deceased, this does not mark the end of our work,” Sheriff Caprice Massey said.

“Our commitment now is to provide the families of Mary, Rowan, Stella, Linsey and Alvin with answers as we learn them. They deserve nothing less.”
