A benefit was held Sunday to help Norma's family.
The Cali Style Low Riders Car Club put on a car wash at a tire shop in Moreno Valley.
The 17-year-old was abducted July 15. Her body was found last week in a field.
On Saturday, two Chili's restaurants donated part of their proceeds to the family.
"We're having a good turnout," said Moreno Valley resident Eddie Salas, who volunteered Sunday. "As a community, it feels real good."
