Well, this kind of thing happens - one never really knows why a young person would fabricate such a story - as to whether they will take her at her word - most times NO. There would be an investigation wherein you B-I-L would be questioned. Of course, he does not need to answer any questions without having an attorney present to assist. So he might want to consider consultation with a local attorney for more guidance in this matter
The lowest of the degrees of a sexual contact offense would be in the Fourth Degree (609.345) and you can CLICK HERE to read more on that law and the possible penalties.
Keep in mind, that a crime of this nature needs to be prove that there was a sexual INTENT and has to be proved beyond a reasonable doubt.
While they will listen intently to the "victim" they should do an investigation with questioning before bringing charges. Again, it would be in his best interest to consult with a local attorney and have one on "stand by" in case such questioning should arise and he become uncomfortable with it. An attorney will be able to protect his rights at the juncture.
