Former NFL defensive tackle Junior Siavii died on Thursday at the age of 43 in Leavenworth federal prison in Kansas.
Anna Armijo, a spokeswoman for the U.S. Bureau of Prisons, said in a statement (h/t Bill Lukitsch and Sam McDowell of the Kansas City Star) that Siavii was found unresponsive and was treated by prison staff before being transported to a local hospital where he was pronounced dead.
According to Lukitsch and McDowell, Siavii has been held under federal detention orders since 2019. He was indicted by a federal grand jury in Nov.
