Com. v. Parker, A., 548 EDA 2023

Abbas Parker was convicted in Philadelphia of first-degree murder, conspiracy to commit murder, possession of an instrument of crime, and firearm offenses related to the shooting of Sherman Williams, another local rap musician, in 2017.
The murder stemmed from a dispute over insulting rap lyrics posted online by the victim, which angered Parker.
After the shooting, a police investigation linked Parker to the scene through an eyewitness, a vehicle license plate, cell phone evidence, and surveillance footage; further, Parker created and released rap videos with lyrics similar to facts of the crime.
Police recovered Parker’s phone during a search linked to a vehicle seen at the murder scene and obtained a warrant to search its contents, revealing evidence relevant to the murder investigation.
At trial, the Commonwealth presented evidence including one rap video in its entirety with sound ("Bloodos") and a muted portion of another ("Notorious"), as well as officer identification testimony regarding Parker’s presence in surveillance videos.
Parker appealed, arguing evidentiary and procedural errors, including the admissibility of rap lyrics, the cell phone search, identification by a law enforcement officer, and prosecutorial misconduct.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Admission of rap video lyrics	Lyrics from Parker’s rap video were prejudicial, not probative, and should have been excluded.	Lyrics closely mirrored actual crime details and were therefore relevant and admissible.	The lyrics were properly admitted as they sufficiently mirrored real-world events.
Suppression of cell phone evidence	The search warrant was overbroad and lacked particularity, so evidence from the phone should be suppressed.	Warrant described evidence as specifically as possible, limited scope to evidentiary value for murder investigation.	Warrant was sufficiently particular and not overbroad; suppression motion properly denied.
Officer’s identification testimony	Identification was based on collective knowledge, not solely on the officer's perception, thus improper.	Officer had sufficient personal familiarity (over a decade of interactions) to provide lay opinion identification.	Officer’s identification based on personal perception was proper under the rules of evidence.
Prosecutorial misconduct in closing	Prosecutor improperly vouched for witnesses in closing arguments.	No objection made at trial; issue not preserved for appeal.	Issue was waived for lack of contemporaneous objection.
