For the third time since Christmas, authorities in St. Louis County are investigating a carjacking.

The latest crime happened Tuesday on the Eden Seminary campus in Webster Groves, where police are searching for two suspects. Police say an SUV pulled up behind a Nissan Maxima and the suspects ordered the driver and passenger out of the car at gunpoint. The stolen car was found later by police in East St. Louis, Illinois.

Carjackings were also reported Dec. 26 in Kirkwood and Sunday in Affton. Authorities are trying to determine if the crimes are connected.
