Jessica wasn't supposed to be in San Bruno.
"She actually switched her day of work to come watch the game with a friend, but she didn't live there, so it was wrong place at the wrong time," said Jim Hammack, a family friend.
Jessica was at her boyfriend's San Bruno home when the explosion happened. Joseph Ruigomez, 19, was severely burned as he tried to save her. He is still in the hospital with second and third degree burns over 40 percent of his body.
Jessica's friends and family tried to focus on her life and not how she died.
"We're trying to just remember how great of a person she was and not think of tragedy and hold her in our hearts and just know that she's in a better place," said Raquel Morales, Jessica's cousin.
Her loved ones came together in Daly City for a vigil. Her parents decided to keep the service private.
"There's a beautiful pink coffin, pearl, which she would have loved because she was very into fashion, just a beautiful person," said Maria Deleon, a family friend.
Jessica's family says she was very good at making friends which was apparent at her vigil.
"She had this great personality, she always brought you up when you were down, she's just a great person overall and she's going to be missed," said Zynal Aziz, Jessica's friend.
Jessica hoped to become a fashion journalist and was taking classes at Academy of Art University in San Francisco.
"She had a lot going for herself and she went young, but we are always going to remember her," said Raquel.
"I feel like I just lost my own daughter. I really, really am going to miss her tremendously. There are no words to express how much I'm going to miss her," said Deleon.
On Saturday, the family will hold a memorial for Jessica and she will be buried on Monday.
