who best to try and turn someone in for Disability Fraud where something might actually get looked at?

I have an acquaintance who by family taught her how to try and get SS Disability, but is pulling such a fraud it's unbelievable. She is out almost every night, been doing volunteer work, modeled, and have pictures from a website showing her doing many activities. She even brags about how busy she is. One of her own doctors in a GAL report stated there was nothing wrong with her from leading a normal life. i don't want to just send an email from a website to someone, but would like to see some sort of action taken. Does the state of WA determine this or is it completely the SS dept?
