Pieces of the puzzle continued to be added in the investigation of the death of Odin Lloyd, where New England Patriots tight end Aaron Hernandez remains a person of interest.

Fox 25 in Boston reports that neighbors around Hernandez's home said they heard shots fired between 3:00 and 3:30 a.m. Monday, though no one called the police regarding the gunshots.

Also, the report indicates that video exists of Hernandez and two other men walking into the house shortly after the time the shots were fired. It also said that about an hour before Hernandez was seen walking into his home, there is video of him walking into Lloyd's home in Dorchester, Mass.
