Former LSU star Demetrius Byrd arrested after allegedly brandishing knife on Miami bus

In Miami, a man once celebrated for a single brilliant catch that helped send LSU to a national championship now sits in custody after allegedly brandishing a knife on a public bus and asking strangers who among them wished to die. Demetrius Byrd's story traces the arc from athletic promise to a career erased by a pre-draft car accident, and onward into a quieter, darker unraveling. The incident — witnessed by passengers who had no part in whatever brought him to that moment — carries the weight of a life that splintered somewhere between the stadium and the street.
