Country music singer Granger Smith’s 3-year-old son has drowned in the family's backyard pool. The child, River, was known to Smith's fans. He appeared in his dad's music videos and on the family's popular YouTube channel, The Smiths. The singer broke the heartbreaking news on Instagram. River's death comes almost exactly a year after Olympic skier Bode Miller's little girl, Emmy, drowned in a neighbor's pool. The Millers are reaching out to the Smiths, offering love and support.
