Gisela Gagliardi, a Twilight fan visiting San Diego for Comic-Con, was hit by a car and killed while running across the street in front of the San Diego Convention Center.

The San Diego Union Tribune first reported the sad news ahead of the convention (which begins later this week): “Comic-Con fans said Gagliardi, who was with a group, had been in line since Sunday for the panel for ‘The Twilight Saga: Breaking Dawn Part 2,’ set for Thursday afternoon in Hall H. The highly anticipated panel will include cast appearances and exclusive footage from the movie. Fans said the convention center staff was about to switch the line, so the beginning became the end, and that she was running to keeping her place in line.”

According to photos on her Facebook page, Gagliardi had attended the event in previous years. 

The New York Daily News has more about the Twilight community response to this tragedy: “Fellow Twi-hards mourned the death on Twitter with the hashtag ‘IPTwiFanG’ and have started an online petition to have a moment of silence before Thursday’s panel for The Twilight Saga: Breaking Dawn – Part 2, which will feature stars Kristen Stewart, Robert Pattinson and Taylor Lautner.”
