Hmm, did it look anything like this perhaps?
1/3200th - f2.0 - ISO 200
1/500th - f2.0 - ISO 200
Took these images recently and wondered if it was the shutter

Doesn't look like typical shutter failure.
It just looks like you were maybe shooting through glass into pretty harsh (Early morning or late afternoon) light and it's refraction of the light and possibly shadows - just guessing.
Have you got any shots taken with the camera since?
