"He was a good kid; never gave me any problems," said Ida Mae Brown.
Ida Mae Brown couldn't stop crying. She misses her grandson, 19-year-old Maurice Brown.
He has a twin brother, and Mrs. Brown says she misses their playful arguments.
"He has a brother. They were always arguing. I miss everything about him," she said.
It was July 25th, shortly before 12:30 a.m. when police were summoned to the 400 block of West Duncannon Street in Olney. That's where an SUV crashed into the side of a church.
19-year-old Maurice Brown was found slumped over, unconscious. It was discovered at the hospital that he had two stab wounds to his chest. He later died.
Police say this is a homicide and so far there have been no arrests.
The Citizens Crime Commission has posted a $500 reward and the city of Philadelphia is posting up to $20,000 for information that leads to an arrest and conviction.
Anyone with information is asked to call the Citizens Crime Commission at 215-546-TIPS or the Philadelphia Police Hotline at 215-686-TIPS.
"We need to get these people off the street," said Santo Montecalvo. "This sounds like a brutal, ruthless killing, and we need to get them."
"Please come forward," pleads Maurice's grandmother. "This could have been your family member. We need some justice for Maurice. Please?"
