What's the best way to contact an investigative reporter?

So there is a lady who I will call "Cecilia" that does investigative reporting for local news stories. She covered a topic of interest and its a reoccurring topic on her segments. I reached out to local news station via the contact form but didn't hear back. What would be the best way to contact her? I am certain whoever does the contact form isn't "Cecilia." I'd like to make sure she can make the decision that my info is good for herself. Trust me it is very juicy stuff on a certain local business. I am planning on writing a blog about it myself but she has a way wider reach.
