Gilley Pool lifeguards Robert Eschenbacher and Ethan Bandy are being credited with saving the life of an 11-month-old boy on Friday.“You train for situations like this but you hope you never have to use the knowledge you’ve learned,” said Eschenbacher. “Today I had to use it. I’m just glad the boy is OK and everything turned out the way it did.”It marks the second time in five days Gilley Pool lifeguards have saved a life.
