Making sentences using expressions I learned from the last class

I watched the TV news yesterday. It covered embezzlement in the a big company.
The news spread out nationwide so fast and hit people very hard in Korea. The worth of that it thing is that's is just the tip of the iceberg. 
They suspected One that one of the employees would embezzle quite a lot of money.
I am not sure about that if that's the case, the employee is going to be fired once he is found guilty of embezzlement.

Hi Tony,

Thanks for giving time to use the expressions we had in our previous class. The expressions were appropriate to use in this topic which is impressive that you came up with this subject. Some words changed because I want you to use other terms instead of the common ones that might be helpful for you to apply and get use to it as well. Also, some were removed so that the sentence won't be too wordy. For example, instead of this:

"The news spread out nationwide so fast and hit people very hard in Korea."

You can say:

"The news spread nationwide so fast and hit people very hard in Korea."

It's only few and I'm confident you'll work on that. Thank you!
