Step-by-step explanation:
Felix committed the crime of obstruction of justice by hiding evidence that was requested by the District Attorney. Obstruction of justice refers to actions that intentionally prevent, impede or interfere with the administration of law during the conduct of legal proceedings or investigations.
Such actions can include destroying evidence, harboring a fugitive, interfering with witnesses, or in this case, concealing evidence. When evidence is required as part of a legal investigation, any act to hide, tamper with, or destroy it can result in criminal charges against the person responsible.
