Emergency responders work a wreck at U.S. 61 South and Redbone Road a little before 7 this morning. Sara Harrison, 30, 108 Shannon Drive, driving a 1993 Toyota Previa, and her 1-year-old son, Isaiah Tilley, were treated and released from River Region Medical Center, a hospital spokesman said. Callie Beasley, 52, 303 North Ridge Drive, driving a 2007 Nissan Sentra, was also taken to River Region, where her condition was undetermined. Beasley’s 7- and 10-year-old cousins were in the car, but not injured. The cars hit when Beasley crossed 61 from Redbone. Harrison was northbound.
