Excerpts from a Chicago Tribune article about an unusual ice rescue overnight in Chicago:

Two people were seriously injured when their Lexus veered off Lake Shore Drive and flipped over on a frozen lagoon in Lincoln Park early Monday morning.

Police were called to the 2200 block of North Lake Shore Drive around 1:45 a.m., after getting reports of a car crashing into the Diversey Harbor lagoon in Lincoln Park. Rescue crews found the sedan flipped over on the ice-covered lagoon. The police department’s marine unit ran two lines of rope across the lagoon as a small team worked to free a man and a woman trapped inside the car.

The team used sleds to move the two to waiting ambulances.  As they worked, police and paramedics watched from the banks of the lagoon.

Both people were taken to hospitals in serious-to-critical condition.
