What to do if your ex is still using your address for government aid

my ex girlfriend, who was living with me is pregnant. while at my house she applied for and was accepted to get food stamps, Medicaid, and WIC. we had some huge problems in our relationship and it led to her moving back with her mom in a completely different county. since I broke up with her she has threatened to "disappear to a place that I will never find her or my child" and has been slandering me. I have also found out that she is still using my address so that she could receive government aid through the county that I live in. what action should I take for this? I know this is fraud and am I in any danger to being legally liable for this if the government finds out she doesnt live here, let alone the county?
