SOUTH PHILADELPHIA (WPVI) --Nary Ly describes her father, Don, as a hardworking man and a fixture on Penn's campus where he sold produce from his fruit cart every day.
"He never stopped working," said Ly.
The morning of April 18, 2013, started like any other. At about 5 a.m., the 68-year-old was loading up his cart in front of his home in the 400 block of Vollmer Street in South Philadelphia.
That's when police say a man approached and stabbed him multiple times, killing him.
Ly's family doesn't believe this was a robbery since their father's wallet was still on him with about $200 in cash inside.
"I want to get this person off the streets," said Ly. "I don't want anyone to be a victim like my dad."
Police have released surveillance video of the suspect.
He's described as a light-skinned black or Hispanic male, 5 foot 8 inches tall, with facial hair and a thin build.
He was seen wearing dark colored clothing, a dark knit hat and black Chuck Taylor Converse sneakers.
The Citizens Crime Commission is administering a $5,000 reward, and the City of Philadelphia is posting up to $20,000 for anyone with information that leads to the arrest and conviction of the person responsible.
