A fatal hit-and-run involving a pedestrian and multiple cars during Monday morning rush hour became even more gruesome as fleeing motorists dragged some of the woman’s remains for miles.

UPDATE: Pa. woman whose severed arm was found miles away from fatal hit and run is mourned: ‘Why didn’t you stop?’

As 6ABC reports, it happened Monday morning on Route 1 in Bucks County, as multiple cars struck and killed the woman but did not stop.

But when human remains were found later in the day miles away from the scene in Philadelphia, the story became more gruesome and inhuman.

This as 6ABC now reports police believe those human remains are from the female hit-and-run victim, identified as 29-year-old Alexandra Ridgway.

Details from 6ABC:

Police say Ridgway was struck by multiple cars and ultimately killed while either walking on or attempting to cross the southbound lanes of Route 1 in Bucks County early Monday morning. The incident closed all lanes of US 1 near Neshaminy High School in Middletown Township.

"We had traffic from 5:30 on, we heard a lot of backing up, beeping trucks, things like that," said homeowner Stacy Allen. "I thought it was an accident because it's usually very good, the (traffic) flow is good, I love living here so I knew it had to be something crazy."

"I don't know what she was doing at 3:30 in the morning unfortunately, and I can't believe anybody didn't stop," said homeowner Tanya Berndt of Middletown Township. "That's ridiculous."

Philadelphia police say they discovered human remains along the 8800 block of Pine Road in the Fox Chase section of Philadelphia shortly after 8:30 Monday morning.

Middletown Township police say their investigation now spans across multiple regions, including Philadelphia and Montgomery County.

None of the hit-and-run drivers have been identified as of yet.
