Alan Hoffmann shook his head.
The trail of Amber Long's killer, from the perspective of her former Philadelphia University professor, has gone cold.
"I hope the police department is able to find the perpetrator," Hoffmann said. "I think the family and the community needs some closure."
Hoffman joined a rally for peace held in Long's name, opposite her apartment at the corner of West Ritner and Bouvier streets in South Philadelphia on Sunday afternoon.

Members of various religious groups and denominations gathered to offer prayers for the Long family and to speak out against violence.Wednesday will mark two months since Long was shot and killed in front of her mother in Northern Liberties.
The 26-year-old woman was gunned down during a robbery attempt on the night of Jan. 19 in Northern Liberties. Two men attacked Long and her 50-year-old mother as they walked to their car from the El on the 900 block of Front Street. Long was shot after her attacker pulled on her purse. She died in her mother's arms.
Last week, Philadelphia Police Capt. James Clark said there have been no new leads in the investigation.
"I have the task force looking into it. They're still following a whole bunch of leads, but right now, unfortunately, I have nothing solid to report," Clark said.
Gene Foschini, who lived on the third floor of Long's building for four years, spoke about the aspiring architect's kindness and potential.
He spoke, he said, to be sure the city doesn't forget her killers are out there.
"It's great that they do this," Foschini said, "helps keep it alive."
