how did the kid die?

ok... when the kid dies, the subtitles were going so fast i did not get to read what happend. all i got was "he was driving a jeep, fell asleep, and ran into the wall. he was fine art first then the wall collapsed." next thing i knew they blamed the guy's best friend for killing their son. what really happned???

i live my life for what i believe is right... even if it is controversialor funny...
