Gasps and sobs filled the St. Croix County, Wis., courtroom on Thursday as a jury convicted Nicolae Miu of first-degree reckless homicide for fatally stabbing 17-year-old Isaac Schuman during a 2022 confrontation at the Apple River in western Wisconsin.
Miu, 54, and his attorneys lowered their heads as Judge Michael Waterman read the verdicts from the jury of six men and six women. In addition to the homicide conviction, Miu, of Prior Lake, was found guilty of four counts of reckless endangerment for stabbing four others in Schuman’s group, and one count of battery against another person.
“It’s been 21 months we’ve been waiting for justice for Isaac Michael Schuman. And we got it today,” Donny Hernandez, the husband of Schuman’s mother, Alina Hernandez, said after the verdict. A large group of family members and supporters stood arrayed behind them, outside the courthouse in Hudson.
Miu, who hung his head as the verdicts were read, had argued he was in fear for his life and acted in self-defense. He will be sentenced at a later date, and faces what one of his attorneys called “substantial, life-altering penalties.”
Prosecutors sought a higher charge of first-degree intentional homicide against Miu but also asked the jury to consider the lesser charges. Defense attorney Aaron Nelson said the defense team was surprised and disappointed by the verdict.
“In many ways, self-defense is a community standard,” Nelson said. “And it’s very dependent upon which group of 12 people within the community you ask.”
Miu had remained in state custody since he was first jailed; after the verdict, Waterman revoked his bail and he returned to jail. The top count against Miu carries a sentence of up to 40 years in prison, with more time possible on the other counts. The sentencing determination lies with Waterman.

Prosecutor Karl Anderson said Miu’s behavior that day revealed his guilt.
