When i was a kid i watched a family died in a car explosion

When i was a kid, around 6 to 7 me and my family lived in a shelter. The shelter had a back road that lead to nowhere, while we were going back from my grandparents house i saw a family driving down the road. one moment they were fine the next the car was on fire it had exploded I showed my mom and she called 911, another car pulled up to try to help but the flames got worse. My mom took us home after that. Years later like a week ago i rn 19 turning 20 remember the incident and dawned on me their didn’t make it.
