Someone is using a yahoo email to try and steal my identity.  Who do I report it to at yahoo so they can suspend the email address?

Just mark the message as spam. .There's nobody to report it to.

You don't report it to anyone. Mark their emails as spam and delete them. 

An example sure would help. It depends on what they are doing. If they are sending you spam emails that have scam links, just ignore them and delete them. Everyone knows they are there. The emails are probably coming from scammers in Europe or Africa. There is really nothing Verizon can do to stop them.

Go to the police first for identity theft.  After they open a case, you can then refer Yahoo to that.  This would also be a good time to put a Freeze on your credit.
