Arteece Nash said she knew something was wrong when on Thursday September 27 she got a call from her mother.
"My mom called me and said something happened to Yahfir, so automatically I'm like something happened to Yahfir," she said.
Eighteen-year-old Yahfir Pettiway-Nash was with his father along the 100 block of North Hobart Street in West Philadelphia. It just after 9:30 in the morning.
"When they told me the area, I'm like nothing that goes on around there is but killings so I know it's something bad," she said.
Pettiway-Nash's father said he took him to that area after his son got a phone call.
"He got out of the car proceeded to walk up the street. I want to say 20 seconds later I heard gunfire," said Dontay Pettiway.
Pettiway-Nash was shot and killed, his cell phone was stolen.
The City of Philadelphia is offering up to $20,000 in reward money for the arrest and conviction of the person responsible. All you have to do is call the Citizens Crime Commission at 215-546-TIPS. All calls will remain anonymous.
"We just want justice. I mean it can't bring my son back, but I just want to know that whoever did this is not out there and be able to do this to anybody else's child," Nash said.
