Police continue to search for evidence in connection to the killing of a semi-pro football player that occurred within a mile from the home of Aaron Hernandez, tight end for the New England Patriots.
Authorities said they plan to return to the NFL player's home on Thursday with another warrant. An investigator close to the case told ABC News that it's believed the football player "destroyed his home security system."
Investigators confirmed the home security system, complete with video surveillance, had been smashed on purpose. A cellphone that was used by Hernandez was also turned over to investigators "in pieces" by his lawyers, law enforcement sources said. 
These new details follow an investigation of the NFL player's home earlier this week in connection to the murder of a semi-pro football player, Odin Lloyd, who was a friend of Hernandez.
The 27-year-old man's body was found on Monday with a gunshot wound to the back of the head by a teenage runner in a clearing of an industrial park in North Attleboro, Mass. 

Police said they believe Lloyd was killed between 1 a.m. and 6 a.m. Monday, but his body wasn't found until 5:30 p.m. that day, according to law enforcement sources. 
Lloyd had gone out with Hernandez and two other men the night before his body was discovered, according to Fox News. 
A source speaking to the MyFoxBoston.com said there's video evidence of Hernandez and two other men wearing hoodies and walking into the player's $1.3 million home. This video footage is said to show them walking into the house just minutes before neighbors reported hearing gunshots between 3 a.m. and 3:30 a.m.
Hernandez hasn't been named as a suspect, but authorities said they continue to investigate any leads in the case. 
"He [Hernandez] has not been ruled out. We are not calling him a suspect, but he is definitely not in the clear," said one police official close to the investigation.
Hernandez's attorneys haven't commented on the investigation, but they did release a statement. 
"It has been widely reported in the media that the state police have searched the home of our client, Aaron Hernandez, as part of an ongoing investigation. 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."
An rental car registered to Hernandez has emerged as a key piece of evidence. Authorities recovered the car in Boston on Wednesday after issuing a be-on-the-look-out bulletin for the vehicle, which was dropped off with a broken mirror at a Enterprise car rental location in Boston. 
A rental vehicle was also found near the body of Lloyd. And a third rental car was searched by police on Tuesday after two occupants attempted to leave Hernandez's residence in the car. 
The Patriots have refrained from commenting on the ongoing investigation. Hernandez has spent the off-season recovering from a shoulder scope.
