[VIDEO] Sinkhole swallows 3 cars as Chicago floods

Officials think heavy rain from Chicago's recent flooding could have led to the water main break that opened up a large sinkhole on the city's South Side, swallowing three cars and sending one person to the hospital.

The Chicago Tribune reported Thursday that neighbors saw the sinkhole open up to about 40 feet wide at about 5 a.m. A fourth vehicle just managed to avoid falling in and was towed away.

The victim's son said his father, who was driving his truck when the sinkhole opened, was hospitalized for "a couple of scratches."
