In forensic medicine, the distinction between various methods of asphyxiation is crucial. Let's delve into the given options:
- Throttling: This involves manual compression of the neck, typically using hands. It doesn't involve any ligature.
- Ligature strangulation: This method uses a cord-like object to apply pressure to the neck. It is intentional and requires a device, such as a rope or wire, which can provide sustained compression. Ligature strangulation aligns with the description of being time-frame sensitive, as continuous pressure is required for it to be effective.
- Gagging: This generally refers to obstruction of the airway via a gag, often focused on the mouth rather than the neck.
- Hanging: This involves a person being suspended by their neck using a ligature. While it relates to ligature use, it specifically describes suspension rather than direct strangulation without suspension.
Analyzing the given descriptions and considering the term "expire if not availed within the stipulated time frame" aligns with techniques that depend on continuous force, bringing us to ligature strangulation as the correct option.
