A driver of a U-Haul truck carrying beer kegs through a tailgating area before the Yale-Harvard game Saturday suddenly accelerated, fatally striking a 30-year-old Massachusetts woman and injuring two other women, police said. It's not clear why the driver sped up, New Haven Police spokesman David Hartman said. The truck then crashed into other U-Haul vans in the lot, an open playing field used for pregame tailgating parties before Yale home games. Tim Walker of Pawtucket, R.I., said he was grilling sirloin tips when he heard the crash behind him. He turned and saw two people lying on the ground.
