Massachusetts State Police have returned to the home of New England Patriots tight end Aaron Hernandez. Two troopers knocked at his door Wednesday morning in North Attleborough, but no one answered.

On Tuesday night, police spent hours there as another group of officers searched an industrial park about a mile away where a body was found Monday. No more details about the body have been released.

Sports Illustrated, citing an unidentified source, reported that Hernandez was not believed to be a suspect in what was being treated as a possible homicide. The magazine says police have spoken with Hernandez.

State police have referred questions to Bristol District Attorney Sam Sutter's office, which declined to comment.
