After days of secrecy in the closely watched investigation, the prosecutor's comments in court provided the first detailed account of Lloyd's killing and the evidence detectives have uncovered.
A jogger found Lloyd's body, riddled with gunshot wounds, in a secluded area of an industrial park near Hernandez's house June 17, McCauley said.
Investigators later found five shell casings at the scene. Inside his pocket, McCauley said, they found a wallet and keys to a car that Hernandez had rented.
Around 2:30 a.m. that same day, the prosecutor said, Lloyd was last seen leaving his Boston home with Hernandez in a silver Nissan Altima.
Less than an hour later, surveillance cameras at the North Attleborough industrial park showed the vehicle heading toward the remote area where Lloyd's body was later found, McCauley said.
"The car goes down there at 3:22," McCauley said. "Four minutes later, the car is visible again. During the interval between 3:23 and 3:27, people who were working the overnight shift hear gunshots."
Minutes later, surveillance video from Hernandez's home security system shows the former NFL player arriving back at his house with two other people, according to the district attorney. Hernandez appears to be holding a firearm, McCauley said.
"The defendant goes walking through the house with the gun in his hand. That is captured in the video. ... And they all go down to the basement," McCauley said. "Once in the basement, the surveillance gets shut off."
McCauley said the gun Hernandez was carrying in the surveillance video has not been found.
