re: Purpose of “Statute of Limitations”

The most serious offenses have no statute of limitations in LA. Anything punishable by life or death, so First and second degree murder, agg kidnapping, first degree rape, and "for any sex offense may be commenced beyond the time limitations set forth in this Title if the identity of the offender is established after the expiration of such time limitation through the use of a DNA profile." Also, if it's any sex offense committed on a victim under 17, the period until the victim turns 28.
