Jumping out of the burning building
<p>Let's imagine there is a building on fire. And a girl is trapped on a 3rd floor. She jumps out of a window cause this is the only way to escape and lands on a fireman who just came to the site.</p>

<p>And.. Kills him by crushing into his body.</p>

<p>Can she be accused with involuntary manslaughter? Why/why not?</p>

<p>The crime often called "involuntary manslaughter", or simply <a href="https://app.leg.wa.gov/RCW/default.aspx?cite=9A.32.070" rel="noreferrer">manslaughter in the second degree</a>, is</p>

<blockquote>
  <p>when, with <strong>criminal negligence</strong>, he or she causes the death of another
  person</p>
</blockquote>

<p>The standards for "criminal negligence" as well as "recklessness" are spelled out <a href="https://app.leg.wa.gov/rcw/default.aspx?cite=9A.08.010" rel="noreferrer">here</a>. The first term is defined as:</p>

<blockquote>
  <p>A person is criminally negligent or acts with criminal negligence when
  he or she fails to be aware of a substantial risk that a wrongful act
  may occur and his or her <em>failure to be aware of such substantial risk
  constitutes a gross deviation from the standard of care that a
  reasonable person would exercise in the same situation</em>.</p>
</blockquote>

<p>You can elaborate the above scenario with some details to make this be a criminally negligent act, but I assume the intent is to have this be a tragic accident. So for example, I assume that she did not see the fireman.
The law does not require you to die in a fire in case there is a remote possibility that you could injure another person in the course of saving yourself. Unless you add some evil intent on the girl's part ("I don't care if I land on that fireman, that's his job"), a reasonable person would act likewise and save their own life.</p>
