The San Diego Convention Center.

The U-T San Diego reports that a 53-year-old woman was struck by a car and killed this morning on Harbor Drive, the street directly in front of the San Diego Convention Center. The victim, whose name has not been released, reportedly dashed into the street to keep her place in line for the “Twilight: Breaking Dawn Vol. 2” panel, which will be held in the Center’s Hall H on Thursday.

An oncoming Subaru hit the woman before she could get out of its path; the Union-Tribune says she was taken to a nearby hospital with serious head injuries and subsequently died. She had been waiting in line for the final Comic-Con “Twilight” panel since Sunday.

Fellow “Twilight” fans are planning to organize a moment of silence and a memorial fund, the newspaper reports.

The sad incident will undoubtedly start another dialogue about whether the fan fervor at Comic-Con has gotten too out of control. While the pop culturally obsessed masses at the massive San Diego event are a very excited bunch, they are generally well-behaved and the staff keeps things pretty orderly. Incidents like this are rare.

The only newsworthy injury in recent years occurred two years ago, when a fan stabbed another fan in the eye with a pen in the Hall H during Comic-Con 2010. Presentations were put on pause for an hour after the incident, which did not result in a fatality.
