What legal action could be taken against me if I kill the alternate myself from other reality?
<p>If "another me" from some alternate reality comes to meet me and I kill him for some reason, and I am caught by police; could I be convicted of any crime in the U.S.?</p>

<p>(This question was originally posted on <a href="https://worldbuilding.stackexchange.com/">WorldBuilding</a> but I was told it would be more on-topic here.)</p>

<p>Under U.S. laws there is no need to identify the victim to charge and convict a person of murder.</p>

<p>Furthermore, the <em>identity</em> of the victim does not offer any defense against a charge of murder under any U.S. law.</p>

<p>(Just to clarify this answer should it be considered in isolation: Given circumstances that are not contemplated in the question, the identity of the victim could <em>contribute</em> to a claim of <a href="/questions/tagged/self-defense" class="post-tag" title="show questions tagged &#39;self-defense&#39;" rel="tag">self-defense</a>.)</p>
