It's the fiercest rivalry in professional sports: the decades-old feud between fans of the New York Yankees and the Boston Red Sox.
But incredibly, a clash between rival fans ended in death for one Red Sox fan, and landed a Yankees fan in court on murder charges.
29-year-old Matthew Beaudoin was on a night out with three friends at a bar in Nashua, New Hampshire...Red Sox country.
As they left, they got into an argument with Ivonne Hernandez. They noticed a Yankees sticker on her car, and taunts flew.
In court, prosecutor Susan Morell said of Hernandez, "She wasn't intimidated by the four yelling at her that the Yankees suck. She put it right back in their face, [The Yankees had] 26 World Series to four."
As Beaudoin walked across the street, Hernandez gunned her car, knocking him down. Beaudoin was rushed to the hospital with massive head injuries.
"I just remember holding his left hand and when I walked away I looked down at my hands they were just covered in blood," says Faith Beaudoin, the victim's sister.
Beaudoin's family made the heartbreaking decision to turn off life support.
Hernandez was charged with second-degree murder. She sobbed after the guilty verdict was announced. As she was led away, her legs buckled under her.
Beaudoin's mother Susan was also in tears after the verdict. "Justice was served," she said.
Hernandez could face life in prison.
