A co-worker lied to get food stamps?

My co-worker yesterday told me she lied to Social Services and told them that the baby's daddy moved out (he was making alot of money) so that they could get food stamps. She said she told them that he moved in with his boss & his boss backed the story up. Do they make home visits to make sure? I'm not best friends with this girl but I'm afraid shes going to go to jail.
