Today a Union County jury convicted Luis Vail-Lopez, 24, of assault with a deadly weapon inflicting serious injury. He was sentenced to serve 33-52 months in prison.
The State’s evidence showed that in September 2022, the defendant ambushed the victim after she finished working third shift at an assisted living facility in Monroe. As the victim sat in her car, Vail-Lopez forced his way into the vehicle and, when she fought back, stabbed the victim multiple times in the leg. He then fled the scene.
Investigators quickly linked this random attack with a separate random attack by a similarly described assailant. In addition to the victim’s identification of the defendant, Vail-Lopez’s cell phone records placed him at the crime scene at the relevant time.
Vail-Lopez was already tried and convicted in February 2025 of the separate assault—a r**e—and is currently serving a lengthy prison sentence. The sentence imposed in this case will be served at the conclusion of that sentence.
“This victim showed incredible courage coming to court and confronting her attacker,” said District Attorney Trey Robison. “Mr. Vail-Lopez is an extremely dangerous man, and my Office was committed to getting him off the streets, and keeping him off the streets, for as long as possible.”
This case was investigated by the Monroe Police Department and prosecuted by ADAs Megan Fallon and Megan Pfuntner.
