Jurors in the murder trial of former New England Patriots star Aaron Hernandez have set out on a bus with a police escort for a tour of several key sites in the case.

The former NFL player is accused of the 2013 killing of Odin Lloyd, who was dating his fiancee's sister.

Jurors on Friday are being brought by coach to several cellphone towers that picked up data investigators used to build a case against Hernandez.

They will then visit the street in Boston where Lloyd lived and the industrial park where Lloyd's body was found.

They are also being taken on a tour inside Hernandez's home.

Hernandez is not allowed on the tour, but lawyers for both sides and the judge are attending.
