A Canadian man has been sentenced to two consecutive life terms in prison after California prosecutors said he spent weeks planning an attack on a woman he met through an online gaming platform before flying across the border to carry it out.
On June 25, 2026, Devin Wolfgang Vanderhoef, 26, of North Vancouver, British Columbia, was sentenced in Monterey County Superior Court for the attempted murders of a Salinas woman and her boyfriend during a violent home invasion that prosecutors described as carefully planned and premeditated.
According to the Monterey County District Attorney’s Office, Vanderhoef also received an additional five consecutive years for personally inflicting great bodily injury and personally using a deadly weapon during the attack.
Quick Facts
- Defendant: Devin Wolfgang Vanderhoef, 26
- Home: North Vancouver, British Columbia, Canada
- Sentence: Two consecutive life sentences plus five years
- Victims: A Salinas woman and her boyfriend (both survived)
- Convictions: Two counts of attempted murder and one count of residential burglary
- Sentencing Date: June 25, 2026
- Attack Date: November 2024
Prosecutors Say the Attack Was Planned for Weeks
According to prosecutors, Vanderhoef met the woman through an online video game and became increasingly fixated on her over the course of approximately a year.
Investigators said he flew from Canada to Monterey County in November 2024, where he allegedly purchased knives, duct tape, and handcuffs before conducting surveillance of the woman’s home and workplace.
Authorities said Vanderhoef even posed as an Amazon delivery driver, carrying what appeared to be a package in order to approach the woman’s residence without raising suspicion.
Home Invasion Turned Violent
Prosecutors alleged that after the woman answered the door, Vanderhoef forced his way inside the home.
During the struggle, the woman’s boyfriend was stabbed multiple times and suffered serious injuries. Despite those wounds, both victims managed to escape outside as the attack continued.
According to prosecutors, Vanderhoef pursued them into the yard, where the boyfriend was eventually able to wrestle away the knife and stab Vanderhoef repeatedly in self-defense.
Authorities also alleged that Vanderhoef tackled the woman as she attempted to return to the house and strangled her until she was unable to breathe. Both victims ultimately survived.
Jury Convicted Him Earlier This Year
A Monterey County jury found Vanderhoef guilty in February 2026 of:
- Two counts of attempted murder
- One count of residential burglary
Jurors also found true allegations that he personally used a deadly weapon and personally inflicted great bodily injury during the attack.
Judge Mark E. Hood later imposed two consecutive life sentences, along with an additional five-year enhancement.
Prosecutors Say He Confessed to Planning the Attack
According to prosecutors, Vanderhoef admitted that investigators had been planning the attack for approximately one month before traveling to California.
Authorities said he told investigators that he intended to “actually kill someone.”
Those statements were presented as part of the prosecution’s case. Court records indicate the jury ultimately convicted him following the multi-day trial.
Companion Testified for the Prosecution
Another Canadian man, Darius Whyte, traveled to California with Vanderhoef and was initially arrested after the attack.
According to the Monterey County District Attorney’s Office, Whyte later pleaded guilty to:
- Assault by means of force likely to produce great bodily injury
- Being an accessory after the fact to a felony
He subsequently testified for prosecutors during Vanderhoef’s trial.
Sheriff Warns About Online Relationships
Following the investigation, Monterey County Sheriff Tina Nieto said the case demonstrates how online interactions can sometimes escalate into real-world violence.
Officials encouraged parents and community members to remain engaged with young people’s online activity and to take reports of online fixation or harassment seriously.
The Case Is Now Closed
The June 25 sentencing formally concludes the criminal case following Vanderhoef’s February conviction.
The investigation was led by Detective Arras Wilson of the Monterey County Sheriff’s Office.
While the sentence brings the criminal proceedings to a close, prosecutors emphasized that both victims survived an attack they described as deliberate, carefully planned, and intended to be fatal.
