How would I correct this sentence fragment:

Richard III supposedly had the young princes murdered. Never found out what really happened to them.

When you have it corrected, please re-post. We'll check it for you.

=)

Nobody ever found out...

No one ever found out...

It was never found out...

It was never discovered...

The world never found out...

ok so if I was going to correct it I would write it this way?

Richard the III supposely had the young princes murered, but no-one ever found out what really happened to them.

Correct! Good job.

(No hyphen between "no" and "one" though.)

Richard III supposedly had the young princes murdered. No one ever found out what really happened to them.

Thank You
