The sister of a Riverside girl killed in a fiery Northern California bus crash last week spoke for the first time Monday and said she hasn't been able to sleep since losing her beloved identical twin.
Marisol Serrato recalled the moments before her twin sister, Marisa, boarded the ill-fated bus tour to Humboldt State University.
"I told her, 'What if I get in an accident and God saves you from that because you are on the waiting list?'" she said. "'You might not go.'"
Marisol was on the same college tour, but she boarded a different bus that made it safely to the university.
"And she told me, 'We think the same,' and I asked her, 'Would you cry for me?'" she said. "And she just smiled at me and she just kind of like hit me a little."
Ten people died April 10 when a FedEx big rig slammed head-on into the charter bus carrying dozens of Southern California high school students. Days before the crash, Marisol had a nightmare.
"I had a bad feeling, I was nervous," she said. "I saw my dad in the dream and he was dressed in all black."
Marisol said she believes it was a sign, but at the time the twin sisters were just excited they both got a seat.
"I can't get that image out of my head when I last saw her," she said. "She was just waiting there with my mom and she was smiling. My mom says she got on the bus happy."
After nearly 24 hours of agonizing over whether her sister had survived the crash, Marisol got the confirmation Marisa was killed.
"My heart wants to break. I keep shaking in the night," she said. "I can't stay still. Her image pops and pops in my head over and over again."
Marisa told Marisol that if she ever died, she could read her journal -- something Marisol has decided to do.
"I think she wants me to move forward with this and do something for her, and that's what I'm going to do," she said. "I think, 'Why me? Why did God still want me around? And why her? Why was it her time?'"
Marisol is expected to receive her sister's high school diploma from Norte Vista High School in June. She has also decided not to attend Humboldt State University.
