Police are investigating the death of a 30-year-old South Philadelphia woman who was fatally injured after stumbling onto the tracks at the SEPTA Lombard-South subway station early Wednesday.
It is not clear yet if she was killed by hitting the third rail when she fell or by a train that struck her more than 2 1/2 hours after she landed on the tracks.
The Medical Examiner's Office will conduct an autopsy to determine the cause of death. The woman's name was not released.
According to SEPTA, a review of surveillance video shows the woman entering the station two hours after service ended.
