BOSTON -- The longtime girlfriend of a Red Sox fan who was hit and killed by a car outside a Nashua, N.H. bar over the weekend said the fight that preceded his death had nothing to do with the notorious Sox-Yankees rivalry, which was widely reported.

Donna Dionne, 29, told the Boston Herald that Matthew Beaudoin, 29, had been trying to defend a female friend who had been punched by Ivonne Hernandez, 43, outside Slade’s Food & Spirits early last Friday.

Hernandez was charged with second-degree murder, aggravated drunken driving and reckless conduct and was ordered held without bail after allegedly mowing down Beaudoin and others outside the bar following the scuffle.

Beaudoin died of massive head trauma later that day.

Dionne said Beaudoin had tried to break up the fight between the two women, and when Hernandez got in her Dodge Intrepid, several people outside the bar noticed the Yankees bumper sticker on it and began chanting, "Yankees suck."

Dionne told the paper the group was just mocking Hernandez but the original scuffle was not about the team rivalry.

She said she had dated Beaudoin for 12 years and the couple had talked about getting married.
