(CNN) — Aaron Hernandez, the former NFL tight end charged with murder in the death last week of an acquaintance, is now being investigated in connection with a double homicide in Boston’s South End in July 2012, a law enforcement source close to the investigation told CNN.
The source gave no indication whether there was any connection between that investigation and Hernandez’s current murder charge.
What is known is that the Boston Police Department has located and impounded a silver SUV with Rhode Island registration that police have been trying to find for almost a year, which is linked to the scene of a double homicide in 2012, the source said.
Investigators believe that Hernandez was renting the SUV at the time of those killings, the source said.
A second man arrested in connection with the killing of Odin Lloyd is also expected to appear before a judge.
Carlos Ortiz was arrested in Bristol, Connecticut, on Wednesday and will have an initial hearing in Attleboro, Massachusetts, District Court as early as Thursday, a source with knowledge of the investigation told CNN.
Hernandez is accused in last week’s shooting death of Lloyd, whose body was found in an industrial park area less than a mile from Hernandez’s home.
He has pleaded not guilty.
New details as bail denied
Hernandez was back in court Thursday to appeal an earlier decision to deny him bail.
A judge at the Fall River, Massachusetts, Superior Court denied his request, saying that bail in first-degree murder cases is very rare, and that Hernandez is a flight risk.
First Assistant District Attorney Bill McCauley, in his argument for why bail should not be granted, provided new details about the investigation.
Lloyd was shot five times, he said.
The first bullet went through his forearm and into his abdomen, suggesting that he tried to raise his arm to defend himself, McCauley said. Lloyd was then shot twice in the back, and once he was down, shot two more times in the chest, the prosecutor said.
In addition, text messages from Lloyd to his sister indicated that he knew he was in peril, McCauley said.
He texted his sister reminding her of who he was with — “I just want you to know,” he wrote.
Hernandez’s lawyers argued that their client had not obstructed the investigation, as prosecutors alleged, and that he was not a flight risk. They offered the use of electronic monitoring and house arrest as options, but were rejected.
Accusation of orchestrating murder
On Wednesday, McCauley said in court that Hernandez “drove the victim to the remote spot, and then he orchestrated his execution.”
“He orchestrated the crime from the beginning, he took steps to conceal and destroy evidence, and he took steps to prevent the police from speaking to … an important witness,” the prosecutor said.
Defense attorney Michael Fee has said that the evidence is circumstantial and that bail should be granted so that Hernandez can return home to spend time with his fiancee and 8-month-old child.
“It is a circumstantial case. It is not a strong case,” Fee said, arguing that Hernandez was not a flight risk and had cooperated with authorities.
Lloyd, 27, was a semipro football player who worked for a landscape company. His sister, Olivia Thibou, told CNN last week that her brother was dating the sister of Hernandez’s fiancee. Lloyd and Hernandez were at a Boston nightclub together the night of June 14, she said.
A ‘model inmate’
During his first 24 hours in jail, Hernandez has been “polite and cooperative” and a “model inmate,” Bristol County Sheriff Tom Hodgson said.
Hernandez was being held in the jail’s medical unit, which is standard for someone who hasn’t been incarcerated before, Hodgson said.
The former pro athlete showed “no apparent nervousness” in jail, Hodgson said, but he noted the difficulty of going from having thousands of people cheering for him to being “just a number.”
While in the medical unit, Hernandez will be locked up for 23 hours a day, with a break for a shower and phone calls, the sheriff said.
