A Portland Carjacking Suspect Now Faces Murder Charges in Northwest Portland Slaying

A recent development out of Portland has sent a ripple through the city's ongoing efforts to grapple with crime, as a suspect already in custody for a violent carjacking now faces the incredibly grave charge of murder. It’s a somber reminder of the interconnectedness of criminal investigations and the persistent pursuit of justice, even when timelines stretch out.

The individual at the center of these serious accusations is 32-year-old Robert Andrew Krummenacker. He was formally indicted on May 14, 2026, by a Multnomah County grand jury for the murder of 37-year-old Andrew J. Nelson. The tragic incident, which involved Nelson’s death, occurred way back on November 29, 2025, in Northwest Portland, specifically near the intersection of Northwest 19th Avenue and Northwest Flanders Street.

Krummenacker now stands accused of second-degree murder and unlawful use of a weapon in connection with Nelson’s death. These new charges are undeniably severe and cast a long shadow over his existing legal troubles. What makes this particular case even more striking is that Krummenacker was already behind bars, having been arrested in March 2026 for an unrelated — yet equally disturbing — carjacking incident.

The carjacking, for which Krummenacker was previously indicted, involved a ride-share driver. Reports indicated that Krummenacker allegedly pulled a gun on the driver, stealing their vehicle in a terrifying ordeal. For that, he faces charges of first-degree robbery and unauthorized use of a vehicle. It’s a testament to the tireless work of law enforcement that these separate, violent acts have now seemingly converged, revealing a clearer, albeit troubling, picture of alleged criminality.

Investigators, one can only imagine, must have been meticulously piecing together evidence over many months. The journey from a violent carjacking arrest to a murder indictment speaks volumes about the dedication required to connect such complex criminal threads. While details surrounding the specific circumstances of Nelson’s murder itself are often kept under wraps during ongoing investigations, the formal indictment signifies that prosecutors believe they have substantial evidence to proceed.

For the family and friends of Andrew J. Nelson, this indictment surely brings a renewed sense of hope for accountability, even as it reopens painful wounds. For the community, it serves as a stark reminder of the challenges Portland faces, but also of the persistent efforts by authorities to ensure justice is served. Krummenacker is expected to be arraigned soon, where he will formally enter a plea to these very serious new charges. The legal process, as it often does, will now take its course, aiming to uncover the full truth.
