Don't tell them any more than necessary. Just tell them that you need to bond a title. They will tell you what info they will need and do a search for a previous owner (within the state that you live in). If no one shows up, which they won't since it was last registered in MN, they will proceed with you getting a bond for it. You will probably need to call your states DMV headquarters for the bonded title, not your local one,
