When you loose a rod bearing the extra clearance between the crank and whats left of the bearing and rod start acting like a slide hammer and all the damage you have is the results. This slide hammer effect snaps pins and pops the pin bosses out of pistons. It can also snap rod bolts. hummm 8,000 rpm = 133.3333 times a second that the slide hammer hits. Looks to me like you simply lost a bearing.. show us a picture of what is left of the bearing.. that might be all we need to see.
