The older Beathard, a 49ers backup quarterback, wrote that his youngest brother "is the sweetest, most humble, toughest and [kind-hearted] people this world had in it."
"I just know Clay is looking at us grieving down here right now saying, 'stay strong,'" Beathard wrote.
Clayton Beathard, 22, and friend Paul Trapeni III, 21, were fatally stabbed on Dec. 21 outside of a Nashville bar.
Nashville police said Beathard and Michael D. Mosley, 37, engaged in an altercation that turned violent after Mosley made "unwanted advances" towards a female friend of Beathard, Trapeni and a third stabbing victim. Nashville police arrested Mosley on Christmas, charging him with two counts of criminal homicide and one count of attempted criminal homicide.
