Broken AISIN timing belt pulleys. Ever see any before

[datarecovery]

This is a new car to me that I bought with the no start engine. Only 42000 miles since last timing belt change . Here's what I found when I opened it up.

Several bolts on water pump  housing were loose. Alternator lower bolt was broken. The tensioner pulley was completely  broken apart so I don't have any pictures of that . Water pump shaft was bent and water composed inoperative. That's why the coloring on the water pump pulley is shows discoloring from the Heat. Who knows what happened in terms of the sequence....

Anyone ever see this on a Lexus? I've had 10 Lexus before, worked as a mechanic 30 years, and I've never seen this before.
