it all started out pretty innocently. three buddies get together, fun night out. it ended with the death of william angel syst. >> he's a guy that's just so warm and welcoming. >> they played pool. they had laughs. they decided to call it a night. they all piled into william's mustang for what should have been an uneventful ride home. >> we were coming up to the merge. i saw headlights. i remember veering to the right and i heard both william and robert scream.
