A woman was killed and three people were injured when a car and an SUV collided at an intersection in St. Paul, city police said Friday.

The car's driver, Melissa Kaltveit, 40, of St. Paul died and her 18-year-old son was hospitalized with noncritical injuries after the collision Thursday afternoon at N. Maywood Street and W. Orange Avenue, police said.

Two 16-year-olds in the SUV reportedly suffered minor injuries and did not require hospitalization.

A preliminary investigation found Kaltveit was driving east on Orange when she failed to stop at a stop sign and collided with the SUV northbound on Maywood, police Sgt. Mike Ernster said.
