Nicolae Miu is accused of stabbing and killing 17-year-old Isaac Schuman of Stillwater, Minnesota while tubing on Wisconsin's Apple River. Four other victims suffered serious or critical torso or chest injuries in the incident on July 30, 2022. Miu told investigators he feared for his life after several people advanced towards him while he was searching for a lost cell phone. Miu was apparently looking for a friend's cell phone in the river but was confronted by tubers who said he was acting sketchy. The encounter escalated, and he apparently punched a female on the left side of her face before Miu was punched, eventually leading to the stabbing.
