Talking to the "regular" police and talking to a federal investigator are two completely different things. At the federal level they have "false or misleading statements"[0] which is a felony with a five year max. People have been convicted and done prison time on this alone based on nothing other than the notes and testimony from a federal investigator. At the state level probably the best they have is "obstruction of justice"[1] which requires things like physically interfering with the police or destroying evidence and even those actions have lesser penalties than "false or misleading statements".

I have a friend who is a federal criminal investigator and his advice when/if the feds show up is to say nothing other than "Do you have a business card? Someone will be in touch." and get a lawyer ASAP.
