One woman was killed, and two others were injured after a U-Haul van crashed into a crowd tailgating before the Yale-Harvard Football game today. According to police, a 30-year-old Massachusetts woman was killed in the accident just after 10 a.m. this morning in a parking lot at Yale. Police spokesman David Hartman confirmed the other two female victims are hospitalized—one in critical but stable condition, and the other with minor injuries. Update: Watch video of the aftermath of the accident below.

The tailgaters had gathered for the 128th game of the Ivy League rivalry. Thus far, it's unclear what caused the the driver of the U-Haul to accelerate and run into the three victims before crashing into a smaller U-Haul—the driver has been taken by police for questioning. The Yale Daily News has identified the driver as a Yale student.

According to the Hartford Courant, photos from witnesses at the scene of the accident showed several kegs and alcoholic beverages inside the two parked U-Hauls-but it was not clear whether the U-Haul involved in the accident also had alcohol in it.

Update: Below, watch video taken from just after the accident occurred. You can hear someone crouched near one victim say, "We're not getting a pulse," as the cameraman notes the ambulance hasn't arrived yet.
