A Washington state fire department employee was arrested Friday for allegedly murdering his wife after the medical examiner declared her manner of death as a homicide.

According to the Clark County Sheriff's Office, Kevin West, 49, was arrested on Friday in connection to the murder of his wife, Marcelle "Marcy" West.

On Jan. 8, firefighters and Washougal police officers responded to the West home after Kevin reported that his wife was having a seizure. He told the dispatcher that she had stopped breathing and was performing CPR, according to the sheriff's office. Medics provided aid when they arrived, but Marcy West died at the scene.

Detectives told Fox News Digital that they believed they had probable cause to arrest West for the murder of Marcy based on his statements and the evidence uncovered during search warrants.

Several people concerned about the couple's relationship contacted local authorities in the days after her death, the sheriff's office said.

Sgt. Christopher Skidmore added that the medical examiner ruled the cause of death as asphyxiation with blunt force trauma to the neck after a criminal investigation was launched, and the autopsy showed indications of trauma to Marcy West's neck.

"There appeared to be financial and relationship troubles that may have been a factor in her death, but the case is still under investigation," Sgt. Skidmore said.
