In Louisiana, the following criminal statutes could be relevant when a death occurs from the delivery of illicit drugs, failure to call 911, or concealment of a body:

1. Delivery of Illicit Drugs Resulting in Death:
   
   • Louisiana Revised Statutes §14:30.1 - Second-Degree Murder: This statute includes deaths caused by the distribution of controlled dangerous substances. If someone distributes or dispenses drugs and it results in another person’s death, they can be charged with second-degree murder.

1. Failure to Call 911:
   
   • Louisiana Revised Statutes §14:502 - Failure to Seek Assistance: This statute makes it a crime to fail to seek assistance or call emergency services for someone in need of medical attention under specific circumstances.

1. Concealment of a Body:
   
   • Louisiana Revised Statutes §14:101 - Obstruction of Justice: Concealing a body could fall under obstruction of justice if it involves tampering with evidence or hindering an investigation into a criminal act.

These statutes are general guidance, and specific circumstances of the case would determine their application. For precise legal advice or interpretation, consulting a legal expert or prosecutor in Louisiana is recommended.
