No, "felony murder" is a homicide committed during the commission of a
felony.

That word again. "Manslaughter" is a particular form of homicide. Homicide
is the killing of one human through the act or ommission of another.
Generally there are five types of homicide: Murder, manslaughter, negligent,
justifiable, and excusable. Some jurisdictions have subdivsions of these
five ("Capital Murder," 2nd Degree Manslaughter, etc.).

In PA, if a robber drops a safe on someone's head while crawling through
a ceiling, it's felony murder.

But if a robber points a gun at the intended victim and pulls the
trigger and the victim dies, it's something higher than felony murder -
it's second degree murder, automatic life without parole.

And if a robber shoots up an armored car driver as Plan A without giving
the driver a chance to live by complying with a carjacking, then it is
higher still - obviously premeditated, first degree murder. Two sentences
are available: Life without parole, and death row.

And if a cop or a getaway car driver has a tire blow out and fatally
crashes during a chase, the DA may press a felony murder charge and the
jury may return a guilty verdict, but then the courts get an appeal added
to their workload because the robber is not why the car had a defective or
underinflated tire or why an overloaded dump truck dropped a piece of
scrap metal on the road. But the DA gets re-elected for "being tough on
crime".
