2008 toyota yaris 2 door hatchback water leak

[knobby bobby]

its been raining really hard today. I opened the hatch and noticed water toward the back of the shelf that covers the spare tire. I removed that shelf and spare tire and found some water on floor toward right side near shock absorber.

I checked the molding around the window and cleared any pine needles.
I bought the car used and found broken glass particles inside rear floor.
Bondo on right rear panel. The car was in Yonkers NY and it looked like someone
smashed the rear window at one time and had it replaced. You can see the car was defaced. The plastic rear winsheild wiper sprayer was slightly melted.

I didnt notice this damage when I bought the car.

Are these toyota yaris hatchbacks prone to leak like this ?
Any feedback will be appreciated.
