Heavy rains in San Antonio rapidly flooded roads, swept away submerged cars and sent some people scrambling up trees to escape fast-rising waters Thursday while firefighters made dozens of rescues across the nation’s seventh-largest city.

The San Antonio Fire Department told CBS News on Saturday that 13 people have been found dead after flooding on highways in Texas.

As San Antonio mourns the loss of at least twelve residents swept from roads during the record flood event Thursday, prayers can be assigned to names, or at least seven of them so far. The death toll from the floods continues to rise, nearly by the hour, and Bexar County officials are beginning to tell us who they are.
