TOWN OF HERMAN, Wis. -

Sheboygan County authorities said two cars have collided in the Town of Herman, killing two people.

The sheriff's office said the collision occurred Sunday about 4 p.m. Both people who died were in one vehicle.

The sheriff's office said Monday the victims were 71-year-old Margaret Lange of Sheboygan and 52-year-old Barbara Killey of Waukesha.

Sheriff's Lt. John Detienne said details are still being sorted out. But he said a car with a single occupant appears to have crossed the center line and collided with the other vehicle containing the two victims.

The single occupant wasn't injured.
