Second thoughts here, you could use both "felony murder" and "first degree murder" (this one more specific).
But some courts prefer to think of "felony murder" as a doctrine of sorts, to differentiate a murder that happened in the comission of a felony. So, for example, a homicide wouldn´t apply.http://www.wisegeek.com/what-is-felony-murder.htm
One aside note:
Importantly, the time component is marked by when the killing occurs, not when death occurs. For example, felony murder could be charged when an elderly person is shot during the crime incident but lingers for ten days, long after the crime is over, before succumbing to her injuries. Her assailant could be charged with felony murder.
