Authorities said San Miguel fatally stabbed Joshua Kinnaman, 18, on April 4, 2023.

Kinnaman died after challenging San Miguel to a fight over comments he had made to the defendant’s girlfriend during a lunch break at a restaurant near John Jay.

San Miguel was found guilty of criminally negligent homicide in October. A new jury was picked on Monday to hear the punishment phase and to determine Jesus San Miguel’s sentence.

The jury heard details from the first trial and viewed a video of the stabbing inside the restaurant.

The video shows two teens going outside to fight. Kinneman was seen pushing San Miguel and then throwing a punch after being stabbed by San Miguel.

“Jesus San Miguel brought a knife to a fistfight. A fistfight he had agreed to engage in,” prosecutor Raul Jordan said. “All because of a schoolyard fight that should have been non-lethal over a girl.”

The defense contended this was a case of self-defense and argued Kinneman initiated the fight.

“The facts are going to show you that not one time does he step forward. Never. He’s walking back the whole time,” defense attorney Charles Bunk said.
