Fall River, MA (SportsNetwork.com) - The murder trial of former New England Patriots tight end Aaron Hernandez began Thursday with opening arguments from both the prosecution and the defense.

Hernandez is charged with the June 2013 killing of Odin Lloyd, a semi-pro football player from the Boston area who was dating the sister of Hernandez's fiancee.

Prosecutors say Hernandez and two other men, Ernest Wallace and Carlos Ortiz, drove with Lloyd to a North Attleboro, Massachusetts industrial park, where Lloyd was shot multiple times and left for dead. A jogger found Lloyd's body on June 17, 2013.

Hernandez has been incarcerated since his arrest on June 26, 2013. He was released by the Patriots later that day.

Bristol County Assistant District Attorney Patrick Bomberg told jurors that Hernandez planned the killing of Lloyd and tried to cover it up.

Defense attorney Michael Fee said his client was innocent and that police never looked elsewhere after connecting Hernandez with Lloyd.

Hernandez has also been charged separately in a July 2012 double-murder case in Boston.
