Imam Amin Muhammad told relatives and friends of Nadirah Ruffin Tuesday that they need to find the "perpetrators of this crime."
The Press of Atlantic City reports there was loud agreement when Muhammad said it was impossible that no one saw anything.
The 19-year-old Egg Harbor Township resident was forced at gunpoint by three men and a woman wearing masks from her cousin's Atlantic City home on March 26.
Ruffin's body was pulled from the Schuylkill River on April 19.
Police said the mother of a 4-year-old son died of a gunshot wound to her head.
