Investigators planned to return to Hernandez's North Attleborough home Thursday with a warrant based on suspicion he intentionally destroyed the security system, including video surveillance, ABC reported, citing a source it described as close to the investigation into the death of Odin Lloyd, 27, a semipro football player.
Lloyd was shot in the back of the head and his body was found Monday in an industrial park about a mile from Fernandez's home.
ABC's sources said a cellphone the Patriots' star had used was "in pieces" when his attorney turned it over to police, and investigators were looking into the circumstances surrounding the hiring of a crew to clean Fernandez' mansion Monday.
"We are not calling him a suspect, but he is definitely not in the clear," a police official close to the investigation told ABC.
Michael Fee, an attorney for Hernandez, issued a statement acknowledging media reports police have searched the home Hernandez shares with his girlfriend, Shayanna Jenkins.
"Out of respect for that process, neither we nor Aaron will have any comment about the substance of that investigation until it has come to a conclusion," Fee said.
Lloyd had been dating Jenkins' sister, Shanea Jenkins, law enforcement sources told ABC.
Shanea Jenkins' whereabouts had been a mystery immediately after Lloyd was killed, but sources told ABC police found her Wednesday.
ABC reported Hernandez and Lloyd were at a Boston nightclub together Friday night and early Saturday, and investigators were reviewing surveillance video from the club.
