Home surveillance video shown to jurors Monday in the murder trial of former New England Patriots player Aaron Hernandez shows him holding what prosecutors say is a gun and leaving his house with two co-defendants hours before the killing.

Hernandez is accused of the June 17, 2013, killing of Odin Lloyd, who was dating the sister of Hernandez's fiancee. Lloyd was found shot to death in an industrial park not far from Hernandez's home.

The video, taken by an extensive surveillance system in and around Hernandez's home, shows him returning home from a night out celebrating Father's Day with his fiancee, Shayanna Jenkins. They are greeted by two Hernandez friends, Ernest Wallace and Carlos Ortiz, who are also charged in the murder. Both men have pleaded not guilty and will be tried separately.

Prosecutors played the video Monday during testimony by Jennifer Fortier, 28, who baby-sat for Hernandez and Jenkins' infant daughter that night.

On one clip, Hernandez can be seen walking through the living room carrying a black object at about 12:45 a.m. Fortier, who was there at the time, testified that she didn't see the object.

The video also shows Hernandez getting into the front passenger seat of a Nissan Altima rental car and leaving at 1:09 a.m. Wallace is driving and Ortiz sits in the rear driver's-side seat.

Surveillance video taken at a gas station south of Boston about an hour later and played earlier for the jury showed Hernandez driving the Nissan. Prosecutors have previously said they went to pick up Lloyd, then took him to the industrial park, where he was shot to death shortly before 3:30 a.m.

The Nissan was returned to the rental car agency later that day with scrapes along the driver's side and a missing driver's-side mirror, according to previous testimony.

Earlier Monday, the judge said she received a note from a juror. He was questioned privately at the bench. Trial then resumed.
