What type of offense is committed when a person causes death through criminal negligence?

When a person causes death through criminal negligence, the offense they commit is classified as Criminally Negligent Homicide. This type of homicide occurs when an individual fails to be aware of a substantial and unjustifiable risk that results in the death of another person. The key element here is the level of negligence; the individual's actions must be a gross deviation from the standard of care that a reasonable person would exercise in the same situation.

Criminally Negligent Homicide is distinguished from other types of homicide due to the requirement of negligence rather than intent or recklessness. It reflects a failure to act appropriately when a reasonable person would have done so, leading to tragic outcomes, such as death.

The other options do not fit this scenario: Manslaughter involves a degree of intention or recklessness rather than mere negligence, while Unlawful Restraint and Kidnapping pertain to unlawful detention or movement of people, which does not relate to causing death.
