A solemn ceremony was held to commemorate the death 100 days ago of 68-year-old Don Ly.
Ly was savagely murdered outside his home in April as he loaded up his fruit cart.
Ly, a refugee from Vietnam, was a fixture in the heart of the University of Pennsylvania's campus where he sold produce for years.
His wife, four children and multiple grandchildren all miss him terribly.
They pray that police will soon catch the person responsible and find out what the motive was and get justice.
"Hopefully somebody comes forward to confess and turn themselves in," said Hoanhl Ly, victim's son.
Police released surveillance video of the suspect hoping for leads.
Those who knew him say Ly had no known enemies. He was not robbed that morning and nothing had been stolen from him.
His long time neighbors attended the ceremony and they are just as baffled as his family and the police.
"He was such a wonderful man that nobody could understand how anybody could do something like that," said Tina Dolpis.
Come forward and confess. How far can you run and how long can you hide? He does not deserve it," said Hoanhl.
