Clutch think something in my clutch went out.

[tigatron]

Was riding home from work tonight and suddenly my motor cut out and back tire locked up.
Pulled the clutch lever and peddled home the last 4 miles.
First thought was maybe the piston seized in the cylinder so I pulled the head and cylinder slid right off no problem.
With the cylinder off I can move the piston freely so now I'm thinking might be clutch related.

Any thoughts?

Never mind... Had light and ripped it apart more; its the connecting rod to crank is locked up.
