After going to the gym yesterday evening, my wife and I headed to my parents house (nearby) to pick up our daughter, who they were watching. We couldn't get near the house - the entire road was filled with cruisers and roped off with police tape...
My dad was in his garage when he heard a skid followed by a thump - he figured someone hit a tree, and went up the driveway to see what happened. That's when he saw the scooter, broken in half by the accident, with smaller pieces scattered all over the road. My dad and two witnesses on the scene called 911 and tried to resuscitate the fifteen year old kid who had been riding it, but no luck. He died on the scene.

When I was in middle school, I was at the lake one day when two kids nearby drowned, but I didn't see it happen. It was still an awful event to be present at. But watching a young kid die in your arms? My dad was pretty flat about it when I talked to him last night, but I can't even imagine what's he's feeling right now.
