sounds like the 1st guy (kegg) had internal injuries. which doesnt suprise me. thats a very common thing with motorcycle accidents im noticing. people are good about wearing leathers more so now then before, but still alot of people fail to realize that even though your body stops, your organs still impact your chest cavity/ribs/etc and can cause serious damage without you showing any trauma visibly other then maybe some tenderness or possibly a swollen abdomen.
