Criminal prosecutions have definite limits by statute in Louisiana. While a capital offense (one punishable by the death penalty or life imprisonment) has no statute of limitations, most felonies must be prosecuted (the prosecution must be initiated) within six years of the offense. There are several felonies against children that have a ten-year period in which to initiate prosecution, those are all sex-related crimes against minors. The hypothetical situation you describe does not include any sexual offenses. You should contact an attorney regarding civil lawsuits or exceptions under which charges may still be filed.
