Former Rice University defensive lineman Stuart Mouchantaf was charged in the March death of former Rice teammate Blain Padgett on Friday.
According to KTRK's Chauncy Glover, Mouchantaf has been charged with delivery of a controlled substance causing death, which is a second-degree felony that carries a penalty of anywhere from five years to life in prison.
Padgett allegedly believed Mouchantaf had given him Hydrocodone, but the pills were laced with carfentanil, causing Padgett to die in his sleep.
Carfentanil is an opioid often used to subdue large animals, per Ottawa Public Health.
