What if a US citizen kills a foreign citizen?
<p>What if a US citizen kills a foreign citizen in another country and in the US?</p>

<p>If any person (citizen or otherwise) kills any person (citizen or otherwise) in the US, they are subject to the laws of that state, or possibly the federal murder statute depending on the specific circumstances (like, &quot;was the victim the president of the US&quot;). The same goes for a murder outside the US – it depends on where the act took place.</p>
<p>There may be special cases where a country claims extraterritorial jurisdiction. For example, the US can prosecute a person for a murder that took place outside the US, if the victim is an <a href="https://www.justice.gov/archives/jm/criminal-resource-manual-1617-extraterritorial-criminal-jurisdiction-18-usc-112-878-970-1116" rel="nofollow noreferrer">Internationally Protected Person</a>. An example is &quot;Head of State&quot;, if the perpetrator is a US national, or is apprehended in the US. Extraterritorial prosecution exists if and only if a jurisdiction has a law allowing it, so you'd have to fill in the details. If I kill a bus driver in France, the US cannot prosecute me, but France can.</p>
