An argument between Red Sox and Yankee fans led to tragedy.

Bartender Tanya Moran said the argument spilled outside, and at least one person in a group that included Beaudoin began chanting "Yankees suck!" when they saw a Yankees sticker on Hernandez’s car.

Hernandez, 43, allegedly gunned her car and struck Beaudoin and his friend Maria Hughes, 21. Hughes had only minor injuries, which Beaudoin’s sister Faith said was because her brother shielded his friend.

Hernandez, of Nashua, was arrested at the scene. She acknowledged she had been drinking and refused to take a breath-alcohol test, said Morrell, a senior assistant attorney general. Hernandez said she had been in an argument with the group.

"She indicated to police that she wanted to scare this group of people. She thought they would get out of the way," Morrell said.

Dan Lamothe of the Red Sox Monster blog petitions the Red Sox to conmemorate the late fan.

Given Beaudoin’s rooting for the Boston Red Sox and his apparent heroic actions before death, we ask that the Red Sox consider honoring Beaudoin’s memory with — at the very least — a day in his honor. It seems like a fitting, honorable tribute, and one that would give Beoudoin’s fellow Red Sox fans and baseball fans in general a chance to mourn one of their own.
