Find, or create if need be, some (preferably Mudblood) habitual drunk or user of other intoxicating substances. Middle their mind enough and convince them they did it as a drunken lark. Make sure they’ve conveniently ‘lost’ their wand while intoxicated. Possibly have them attack the DMLE personnel investigating, babbling mad rubbish before letting slip a bragging confession. Potentially rig them to die in custody.
I believe this would be fairly easy for me to accomplish, if it were deemed a useful plan, of course.
