Investigators are looking at former New England Patriots star Aaron Hernandez as a possible suspect in a 2012 double murder in Boston, reports CBS Boston station WBZ-TV.
Boston police conducted a search of Hernandez's North Attleborough, Mass., mansion early Friday morning in connection with the double homicide, WBZ says.
The 23-year-old Hernandez was arrested Wednesday, and accused of orchestrating the execution-style shooting of his friend, semi-pro football player Odin Lloyd, allegedly because Lloyd had talked to the wrong people at a nightclub.
He was denied bail at a hearing Thursday in a Massachusetts courtroom, where a prosecutor said a Hummer belonging to Hernandez turned up an ammunition clip matching the caliber of casings found at the scene of Lloyd's killing.
Hernandez's lawyer argued his client is not a risk to flee and the case against him is circumstantial.
Police say Lloyd's body was found near Hernandez' home. Prosecutors assert Lloyd was slain execution-style.
The double homicide occurred in the early morning hours of July 16, 2012, in Boston's South End.
Daniel Jorge Correia de Abreu, 29, and Safiro Teixeira Furtado, 28, both of Dorchester, were killed when someone fired at the BMW they were in.
A third person was wounded. At the time, police said there were two other people in the vehicle, but both ran off before officers arrived.
Sources tell WBZ-TV investigators now believe Lloyd may have had information about Hernandez's alleged role in the double murder.
"We're following evidence, following the leads," Suffolk County District Attorney Dan Conley told WBZ-TV.
On June 16, the night before the slaying, a prosecutor said, Hernandez texted two unidentified friends and asked them to hurry to Massachusetts from Connecticut. A few minutes later, he texted Lloyd to tell him he wanted to get together, the prosecutor said. Authorities said surveillance footage showed the friends arriving, but they did not say who fired the shots.
Meanwhile, Massachusetts State Policeearly Friday afternoon, hours after a Connecticut judge ordered a third suspect turned over to Massachusetts authorities.
New Britain State's attorney said investigators arrested the 27-year-old Carlos Ortiz in Bristol on Wednesday.
Ortiz was charged in Connecticut as a fugitive from justice. His public defender, Alfonzo Sirica, declined to comment about the case.
Also Friday, Massachusetts authorities said officers had recovered a car linked to Wallace.
The Patriots, who cut Hernandez following his arrest Wednesday, drafted him in 2010 and signed him last summer to five-year contract worth $40 million.
