Daij'e Hines was heading to an appointment on Friday morning, but Friday afternoon her mother received a call that her oldest daughter never made it there.
"At 2:00 we found out that it was my baby," said Michelle Hines.
It happened near the 49th Street SEPTA station around 10:30 a.m. Daij'e was home-schooled, and family members say last they knew she was on her way to therapy.
On Friday afternoon, police said they were investigating this as an accident, but her family expects foul play.
As they look for answers, they also seek peace for the young woman they lost too soon.
"She was the kindest of girls, such a sweet spirit. A happy spirit about her," said family friend Linda Salley.
Family and friends held a vigil Saturday night that ended with participants releasing balloons for Daij'e into the night sky.
Funeral arrangements for Daij'e are still being organized.
Meanwhile, the family says they continue to be in touch with police regarding the investigation.
