NASHUA, N.H. -- After a Red Sox-Yankees argument spilled outside a bar, a Yankee fan aimed her car at a group of people to scare them and didn't brake, hitting and killing a man, authorities and witnesses said.

The Yankees fan, Ivonne Hernandez, was arraigned Monday on reckless second-degree murder and drunken driving charges and was held without bail. She did not enter a plea.

Hernandez, 43, was speeding early Friday toward a small group that included the man, Matthew Beaudoin, 29, and never hit her brakes, a prosecutor said Monday.

"She accelerated at a high speed for about 200 feet. She went directly at this group of people," prosecutor Susan Morrell said.

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

Beaudoin died of massive head trauma at a hospital, Morrell said.

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

Hernandez's public defender, James Quay, did not immediately return a call seeking comment.

Authorities won't describe the argument, but witnesses said it heated up when Hernandez identified herself as a New York Yankees fan. Like the rest of New Hampshire, Nashua, 45 miles northwest of Boston, is Red Sox country.

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

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