Criminal laws, namely what is illegal and can result in a conviction and loss of freedom by imprisonment, are prescribed by Indiana and federal statutes. The Indiana penal act is set forth in the Indiana Code in Title 35 www.in.gov/legislative/ic/code/title35 covering Criminal Law and Procedure.
On July 1, 2014, the entire Indiana criminal code will change how criminal offenses are classified. At present, the long-standing system, has been letters, with the lowest misdemeanor being a class C misdemeanor up to a class A misdemeanor. The maximum penalty for these lesser crimes is a year of imprisonment. Under the new system, felonies will be Level 1 (lowest) through Level 6 (highest). Murder, as now, will remain its own crime, murder.
