Northern Indiana authorities are reporting that two people drowned and two others were left hospitalized in critical condition after an SUV plunged into a pond Tuesday afternoon.

Mishawaka firefighters were called to the scene and pulled one adult and three juveniles from the fully submerged SUV after it entered a retention pond in the city just east of South Bend.

Officials from the St. Joseph County’s coroner say two crash victims who were pronounced dead had died from drowning, meanwhile the other two remain in critical condition.

Local roads were icy Tuesday afternoon, but officials are still investigating what caused the SUV to enter the pond.
