PORTLAND, Ore. (KOIN) — A man has been arrested in connection with the shooting death of Clark County Detective Jeremy Brown.

According to the Vancouver Police Department, Guillermo O. Raya was arrested in Salem by the U.S. Marshals Service Pacific Northwest Violent Offender task force and the Salem Police Department.

Raya is one of three suspects in the killing of the deputy. The other suspects, Abran Raya-Leon, 28, and 35-year-old Misty M. Raya, were arrested in the early hours of Saturday after an extensive search.

Investigators with the Vancouver Police Department — the lead agency on the investigation — said they were arrested initially on unrelated felony warrants.

Court documents reveal new details about the investigation and manhunt involving the shooting death of the deputy.

Detectives were watching an apartment associated with Lani Kraabell, according to court documents obtained by KOIN 6 News. The law enforcement officials were watching two people in particular – Misty Raya and Abran Raya Leon, also known as Junior and Guillermo Raya.

When Kraabell drove into the complex in a silver Toyota SUV, Brown was sitting in a jeep nearby.

Investigators reported hearing what they thought were gunshots in the area and spotted the same silver Toyota SUV fleeing the scene with two men inside. Those two people were believed to be Guillermo Raya and Abran Raya, including one woman they think was Misty.

Investigators then followed the Toyota out of the complex.

In the meantime, apartment complex residents around that time saw that Brown had been shot in the chest, reportedly while sitting in his vehicle.

Brown was later taken to the hospital, where he died.

Law enforcement officials eventually found the SUV crashed and abandoned near I-205 and Padden Parkway. Documents state that officials eventually found Misty Raya and Abran Raya in the backyard of an unoccupied house and took them into custody.

According to those same documents, Misty and Abran Raya told detectives they knew they were being investigated for several alleged crimes and knew they faced the chance of arrest. The two told investigators that Guillermo Raya was paranoid that he was being followed that day by law enforcement.

Once at the Pointe Apartment Complex, Misty Raya reportedly said Guillermo Raya went outside to try to figure out who was watching them, after approaching what detectives believe was Brown’s vehicle. ,

Misty Raya later said there were words exchanged and then gunshots. She said Guillermo Raya came back carrying a large, silver revolver and allegedly told them, “He shot me first.”

Police say details on the arrest of Raya are not available.

Raya will be extradited to Clark County to face charges related to the shooting of Clark County Sheriff’s Office Detective Jeremy Brown, said VPD.

Police say additional information will be released as it becomes available.
