Hernandez, 23, has already been charged with murder in the June 17 shooting death of the 27-year-old Lloyd, of Dorchester. His body was found in an industrial park near Hernandez's home in North Attleborough, Mass.

Morrell said Tuesday police searched the same home in Bristol in connection with both the double-homicide probe as well as Lloyd's murder case. CBS Boston previously reported that the Bristol home in question was that of Hernandez's uncle. According to the station, on Friday, police had a car towed from the home that matched the description of a vehicle police had been looking for in connection with the 2012 double-murder.

Safiro Furtado, 28, and Daniel Abreu, 29, were gunned down July 15, 2012 as they sat at a traffic light in Boston's South End. A silver SUV with Rhode Island plates was reportedly seen speeding away from the drive-by shooting. No arrests have been made in the case.

Sources tell CBS Boston that Lloyd may have been executed because he had information about Hernandez's possible involvement in the double-homicide.

Hernandez, who was released from the New England Patriots last week following his arrest, is being held without bail at the Bristol County House of Corrections on a charge of first-degree murder in the death of Lloyd. 

He has pleaded not guilty.
