Fatal Car Accident Killed My Brother

On June 23,2017, my little brother Ivan and his girlfriend were involved in a fatal car accident in California and passed away. It was our annual family trip and we were all headed to Hollywood. Ivan and his girlfriend were riding in their own car on the I-10 when Cherrelle got distracted by Ivan trying to fix the passenger side window. Witnesses claimed to see the passenger messing with the window then soon after the car went left and hit the cement median and then swerved to the right and his girl lost control and went up a hill and the car flipped multiple times. Both were ejected from the vehicle and passed away. Due to this very unexpected tragedy we were not prepared for these expensive, so I am asking for any help anybody can give so we cremate my brother. Thank you all so much
