Start by checking the Maine laws to know for sure if there is a timeline. Some states have websites you can go to for research. This would probably help if you are going to work a chain of command.
You have two ways to go with complaining. One is to talk to a detective Sgt (or Sheriff or Chief depending upon how large the department is). The other is to talk to your state representative. You may or may not get anywhere with this, it depends upon how responsive your rep is. Some of them just forward the complaint to the LE dept, some with check into it. I guess it matters how far away re-election time is.
Good luck.
