An investigation continues into the mysterious death of Michelle Lozano.
The girl's mother, Eva Ramos, said she last saw her daughter Sunday morning when the teen took a city bus to meet her boyfriend, but she never arrived.
Her nude body wrapped in plastic, put inside a plastic container and dropped over a barrier was found late Monday night.
"I wish justice can be served and that they find whoever did this to my daughter," said Ramos, adding that her daughter was very happy, had lots of friends and was liked by everyone.
Organizers of the vigil spent the day dropping off flyers with the victim's picture on it to drum up support.
A crowd began gathering for the vigil about 6 p.m. across the street from Lozano's Lincoln Heights home.
"She was the one to go up to you and say 'Hi,' but she wouldn't hold your hand, she would give you a hug to let you know that she was embracing you," said Lozano's family friend, Richard Mangaser.
"There's hundreds of people here to celebrate her," he added. "She was a very dedicated person to the community. She was very loved. And it shows that we're not going to stand for this. Hopefully with the pressure of all this media attention and all this community coming out and speaking up, whoever did this gets caught."
An autopsy on Lozano's body was conducted Thursday. However, the coroner's office did not releasing the cause of death.
