criminal-law international jurisdiction murder
If a murder was committed in Antarctica and it was unclear who did it, who would investigate?
<p>If a murder were committed in Antarctica and it was unclear who did it, what country/agency would investigate? And, if the guilty party were identified, who (if anyone) would have the authority to arrest them?</p>

<p>Various countries have jurisdiction in Antarctica, see <a href="https://en.m.wikipedia.org/wiki/Antarctic_Treaty_System#Legal_system" rel="nofollow">https://en.m.wikipedia.org/wiki/Antarctic_Treaty_System#Legal_system</a>.</p>

<p>The geographic limits of each country's jurisdiction are well defined. The USA has jurisdiction if no one else does.</p>

<p>In the most cases, the country of the citizenship of the victim would do the investigation. If the crime was committed on an Antarctic base running within a specific jurisdiction, such jurisdiction would be also given and investigation would be probably done by that country as well.</p>
