Officials are afraid that a man accused of strangling his wife, abusing her for years, humiliating her in front of others and threatening her may be at risk of committing a murder-suicide, say court records.

A deputy prosecutor is trying to ensure that the man is not released from jail.

Peter D. Dunphy, 29, of Oak Harbor is facing charges of assault in the second degree, interfering with the reporting of domestic violence and felony harassment; all the counts were charged as domestic-violence related.

A judge in Island County Superior Court ordered Dunphy held on $300,000 bail, but Deputy Prosecutor Michael Safstrom filed a motion to revoke pretrial release altogether. Judge Alan Hancock will hear the motion on Monday.

Dunphy “has exerted nearly absolute control over the victim for years,” Safstrom wrote, “as evidenced by his ability to force her to … tolerate abuse of herself and her children without reporting to law enforcement.’

“The Defendant,” he added, “has cultivated helplessness in the victim through rituals of dehumanization, violence and threats of violence towards the victim and her family.”

Dunphy violated a court order by asking his parents multiple times to contact the victim — his wife — and persuade her not to press charges. His father reportedly contacted the victim’s mother and falsely claimed that the prosecutor wanted the victim to “drop the charges,” Safstrom wrote.

Safstrom also noted the seriousness of the alleged strangulation, which occurred July 11. The woman had bruising around her throat, “exhibited symptoms consistent with a lack of oxygen to the brain, had begun throwing up and was taken to the hospital via ambulance,” he wrote.

In addition, court documents show that Dunphy allegedly threatened to kill the woman and the children on multiple occasions — on one occasion allegedly putting a knife to her throat.

The woman told police that Dunphy had been in the Army but “wasn’t right” after his last deployment. He started smoking “spice” in the Army and now smokes it every 10 minute; he was medically discharged from the military for mental issues last year, the police report states.

The woman finally reported the alleged abuse on July 12. She told police that he pushed her down, choked her and broke her phone when she tried to call police the night before. He told her he should have “finished and just killed her,” according to Gravel’s report.

Dunphy threatened to leave with the children and put them in the car. He made her beg in order to get the kids back. He also threw her car keys on the roof and a pan of her lasagna in the yard, telling her to clean it up.

According to the police report, the woman was terrified that Dunphy would hurt the children and has also been abusive to them.

In an interview with police, Dunphy disputed the claim that he strangled her; he said he “pushed her shirt” under her chin and stopped after she told him she couldn’t breath, Gravel wrote. He admitted to knocking her down, saying he was mad because dinner was late.

Dunphy also allegedly admitted to throwing her phone when she tried to call police and to making her beg.

The officers noticed aluminum foil smoking devices in the kitchen with residue Gravel identified as “spice,” which is synthetic marijuana.

Dunphy’s attorney did not return a call for comment.
