Vallejo cop allegedly told ex-girlfriend he knew how to dispose of a body, would file a missing person’s report if she tried to hide

When the woman reported Ronald Dupree's alleged stalking to Vallejo police, she said she was told they'd look into it, according to authorities.

RICHMOND — A Vallejo police officer was arrested here on Valentine’s Day after his ex-girlfriend reported to Oakland police that he’d threatened and harassed her for months after their relationship ended, according to law enforcement sources.

Ronald Dupree, 29, of Dixon, was arrested Feb. 14 on suspicion of domestic violence, stalking, and criminal threats, but has already been released from Santa Rita Jail in Dublin. No charges have been filed against Dupree and it’s unclear if his case has been sent to the Alameda County District Attorney’s Office for review.

Oakland police raided Dupree’s Dixon home in search of three guns registered to him. They found and seized two firearms, according to law enforcement sources.

The alleged victim is Dupree’s ex-girlfriend, a Bay Area woman whose relationship with Dupree ended last summer. She told Oakland police that at some point — it’s unclear when — she reported Dupree’s conduct to Vallejo police and was told they’d “look into it.” She later received a phone text from a burner application stating, “I hope calling Ronnie job finally ran him away from you” and “you should’ve died a long time ago.”

So far, Vallejo police have only publicly confirmed that Dupree, who joined the police force in 2020, is on administrative leave, and declined to publicly comment further. Last year, he was given the Mothers Against Drunk Driving Award for arresting DUI drivers and the same year earned the department’s medal of courage award.

This scandal comes in the wake of widespread outcry over the Netflix documentary “American Nightmare,” which has generated hundreds of negative comments from people angry over Vallejo detectives accusing a woman who’d been kidnapped and raped of faking the whole thing.

According to Oakland police, Dupree allegedly made unwanted attempts to rekindle their relationship, but that his behavior escalated after she informed him the dog they used to share was at the veterinarian. Dupree allegedly paid the bill, then demanded reimbursement or for her to get back together with him, she allegedly told police.

After that, Dupree started texting or calling her dozens of times per day, often from a blocked number, the woman reportedly told police. She alleged that Dupree threatened her, adding that he knew how to dispose of a body, and that he would file a missing person’s report to locate her if she ever tried to hide, authorities said.

Dupree was arrested by Oakland police in Richmond one day after the woman came forward with her report.
