"Defendant Kiarra Marie Price, then 20 years old, along with two friends, participated in a robbery of Benjamin Merrill during which one of them needlessly and senselessly shot and killed 22-year-old Merrill."
I'm not sure that Justice Stewart needs to say both "needlessly and senselessly". Seems a bit overkill, if you'll pardon the pun.
Though I agree that the killing was needless. Senseless, even.
