A brother and sister were killed in a car crash in Fullerton.
Twenty-three year old Oscar Tinoco and his 17-year-old stepsister Valeria Tinoco died after their car crashed into a tree.
This tragedy isn't the first for the Tinoco family.
Maria and Fidencio Tinoco lost their oldest son Marine Lance Corporal Hugo Lopez in Iraq almost 10 years ago.
Family friends and Valeria's La Habra High classmates are paying tribute to the siblings on social media.
A GoFundMe page has been created to help pay for Oscar and Valeria's funeral expenses.
