Interestingly an over-whelming majority chose "first-degree murder".
Now I'm not sure if that's because of personal wishes, or thoughts based upon law... but since we're getting closer to Harlow's trial, I'd like to know the reason as to why you chose what you did... assuming you don't mind sharing.
Meanwhile... here's the Pennsylvania Crimes Code:
§ 2501. Criminal Homicide:
(a) Offense defined: A person is guilty of criminal homicide if he intentionally, knowingly, recklessly or negligently causes the death of another human being.
