LNP newspaper reports that 41-year-old Wilberto Melendez was arrested last week after a traffic stop in York County.
He is charged with criminal homicide, firearms crimes and witness intimidation in the slaying of William Cooper Jr., who was found with gunshot wounds Oct. 27 on a Lancaster street.
Prosecutors allege that he opened fire on Cooper and another man after an argument.
Jurors acquitted Melendez in 2016 of the November 2014 death of 32-year-old Jeremy Torres, which authorities said occurred after he was denied entry to the party.
Court documents don't list an attorney for Melendez and a listed number for him couldn't be found Saturday.
