A source close to the investigation of a Boston homicide told Sports Illustrated that police believe Aaron Hernandez' role in the murder is substantial enough that the NFL player will likely be arrested, though the nature of the charges haven't been released.

Police served the New England Patriots tight end with a search warrant on Tuesday and investigated his North Attleboro, Mass. home. Police returned to his home again today after they discovered a surveillance camera at the house was intentionally destroyed and cleaners were hired on Monday to scrub the premises. To add to the suspicion, Hernandez' cellphone was allegedly smashed to pieces when his lawyer presented it to the police.

"[Hernandez] has not been ruled out. We are not calling him a suspect, but he is definitely not in the clear," a police official close to the investigation told ABC News.

Still, an anonymous source said that forensic evidence places a vehicle driven by Aaron Hernandez to the crime scene, according to Boston's Fox 25 News. The station also reported that Hernandez visited a local bar with the victim, Odin Lloyod, on the night of his death. A jogger discovered Lloyd's body in an industrial park a mile from Hernandez's home on Monday.

Hernandez's troubles date back to his days in college, according to SI.com The sports website uncovered two occurrences involving firearms and the police, which the professional athlete was linked to. He was also involved in a civil lawsuit by a man that accused Hernandez of a shooting that caused the plaintiff to lose an eye. 

News helicopters followed Hernandez today as he left his home for Gillette Stadium, the home arena of the New England Patriots. When he left the arena and stopped at a local gas station several reporters rushed to this SUV.
