Authorities find skeletal remains inside car on fire

12/26 update:

KAUKAUNA, Wis. (WBAY) - Kaukauna Police say the Dec. 23 death of a woman in a car fire is not considered suspicious.

Police say they are "confident" that the driver was an elderly woman from the Fox Valley, but testing is being done to confirm her identity.

On Dec. 23, at 2:30 a.m., rescue crews were called to Holly Ct. along the Fox River for a car on fire on the railroad tracks.

Remains were found inside the car.

Police believe the victim became confused and mistook the tracks for the road.

Police believe the woman's tires may have flattened, which caused sparking between the car and the tracks. That sparking may have caused the vehicle to catch fire.

It could take several weeks to positively identify the victim, police say.
