In re D.N., 65 A.3d 88

D.N. and Palmer planned to rob Ronald Robinson in July 2008; beating began in an alley with D.N. present and taking cash and car keys.
Hickman, an informant, testified D.N. admitted involvement and recorded statements corroborating participation.
Robinson was beaten, dragged into a dumpster, and died from major blunt-force trauma with concrete fragments found at the scene.
D.N.’s fingerprint matched on a Chrysler; Robinson’s car keys were later missing from the car, suggesting possession by D.N.
Trial court found D.N. guilty of robbery and felony murder but acquitted the armed-forensic elements; it credited Hickman’s testimony and did not require withdrawal for accomplice liability.
On appeal, D.N. argues insufficiency of evidence to connect the killing to the underlying robbery and challenges the court’s legal standard for accomplice liability.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether evidence supports felony-murder liability for an accomplice	D.N. argues no proof that killing was in furtherance of the common plan	State contends killing was within common design or natural consequence	Affirmed: killing tied to common design and natural consequence under accomplice liability
Whether the trial court misapplied the felony-murder standard for accomplices	D.N. asserts misinterpretation of ‘in furtherance of’	State asserts correct application of case law	Affirmed: court correctly applied felony-murder doctrine for accomplices
Whether the alleged corroboration of Hickman’s testimony by the wife’s testimony was harmless error	D.N. says corroboration relied on erroneous fact	State argues corroboration was not the sole basis for credibility	Harmless error: credibility finding supported by multiple corroborating factors
Whether the factual finding about Hickman’s knowledge was clearly erroneous	D.N. claims Bevilacqua testimony contradicts Hickman’s knowledge	State contends evidence supports corroboration of Hickman	Harmless: record supports credibility and the judgment was not substantially swayed
