San Antonio, Texas
A large, ruptured sewer line plus several inches of rain may have been the cause of a sinkhole that opened up in southwest San Antonio on Dec. 4, 2016. The sinkhole swallowed two cars, killing an off-duty sheriff's deputy and injuring two more people.
As firefighters worked at the site, a few collapses widened the sinkhole, exposing the rescue team to raw sewage.
"This is tragic and surprising," Chief Charles Hood of the San Antonio Fire Department told WOIA. "Someone is driving 40-50 mph and doing the things we do while driving like listening to music and you have the road fall out form underneath you. That's a very sad situation."
