The Minnesota Methamphetamine Offenders Registry was approved last July but has just come online this year. A search can be done with an exact match on the last name, or select a county to identify all records. Other states have approved the creation of a database of people convicted of manufacturing meth but only Tennessee currently has this boutique criminal records site.
The Minnesota Bureau of Criminal Apprehension also maintains other criminal offender databases.
homefacts.com has Sex Offender Search and seized meth labs. This would make a great addition
