Melissa Lees, 21, and Caitlin Hennessey, 22, both of the 800 block of Barlow Street, died in the crash just before 2:00 a.m. at the intersection of Byberry and Worthington roads.
Police say the driver, who has not yet been identified, lost control of her speeding SUV and it clipped a utility pole.
The impact sheared off a rear passenger door and threw Hennessey from the vehicle. However, she was snagged by the vehicle and dragged across the intersection until it finally came to stop.
Lees, who was riding in the front seat, was also killed in the crash.
The driver, also a young woman, was injured in the crash and is being treated at the hospital. The extent of her injuries are not known.
She was also undergoing tests to determine if she was driving under the influence. Police say she appeared to be intoxicated.
No charges have been filed so far.
