The stabbing -- that occurred underground on the platform or near the stairs leading from the sidewalk at 5:47 p.m.-- was the result of an argument, investigators said.
When police arrived, they found a 22-year-old man bleeding on the ground suffering from two stab wounds to the chest. He was rushed to the hospital where he was pronounced dead at 6:27 p.m.
SEPTA released a picture of the stabbing suspect from their surveillance on Wednesday.
"They see him in the area on a regular basis and they are familiar with him.
