Police on Thursday night were back at the Massachusetts home of former NFL player Aaron Hernandez, according to a law enforcement source with knowledge of an ongoing investigation into an unsolved 2012 double homicide in Boston. Hernandez, who is being investigated in connection with that 2012 case, is accused of orchestrating the killing of a man whose body was found last week less than a mile from Hernandez's home.

Massachusetts State Police late Thursday said they were seeking a man as an "accessory after the fact" in the death of Odin Lloyd, who was found less than a mile from the home of former NFL tight end Aaron Hernandez.
A North Attleboro Police Department tweet linked to a poster that described Ernest Wallace as being armed and dangerous.
In most states, accessory refers to aiding someone suspected of committing a felony.
Hernandez is charged with first-degree murder in the Lloyd case.
Authorities are seeking the public's assistance in locating Wallace, who was described as being his 40s and having a heavy build. Police also are seeking a silver/gray 2012 Chrysler 300, allegedly last seen being operated by Wallace.
While Hernandez stood in court this week, police were combing a condo he rented to search for evidence in the case against him.
Inside the condo, a district attorney said Thursday, detectives found ammunition for a .45-caliber weapon -- the same caliber weapon that investigators believe was used to shoot Lloyd last week.
Hernandez is accused of orchestrating the killing of Lloyd, a 27-year-old semipro football player whose body was found last week in an industrial park. He has pleaded not guilty.
He's also being investigated in connection with an unsolved 2012 double homicide case in Boston, a law enforcement source close to the investigation told CNN.
The source gave no indication whether there was any connection between that investigation and Lloyd's killing, which drew national attention as Hernandez, a 23-year-old who was once one of the NFL's most promising rising stars, became a high-profile focus of the investigation.
In court, prosecutors have described witness accounts and surveillance footage that they argue solidifies their case against Hernandez.
But, according to First Assistant District Attorney Bill McCauley's arguments in court this week, one key piece of evidence apparently hasn't been found, the gun investigators believe was used to kill Lloyd.
Inside a Hummer registered to Hernandez parked in front of the condo he leased, McCauley said Thursday, investigators found a clip to a .45-caliber firearm.
Search jars neighborhood
By Thursday evening, the Hummer was no longer parked at the condominium complex in Franklin, Massachusetts.
Authorities towed it away after they scoured the area, neighbor Carol Bailey said.
The small condo Hernandez rented near the highway looks drastically different from Hernandez's large house with a plush, green lawn about 10 miles away in North Attleborough, where over the weekend police patrol cars filled the driveway as search dogs and detectives scoured the property.
At the condo complex about 20 minutes away, the police search Wednesday was a jarring sight, Bailey said, noting that she saw them using a dog to sniff for evidence and also carting in a ladder truck to get at the building's roof.
"We've never had the place crawling with cops," she said. "This is a very peaceful, quiet community. This doesn't happen here."
The retired biology professor said she never spoke directly with Hernandez, but she had seen him at the complex, wearing hooded sweatshirts in an apparent attempt to fly under the radar.
When police questioned her on Wednesday, Bailey said she told them she never saw anything suspicious going on in the condo next door.
"No suspicious activity, no girls, nothing other than just typical guy stuff. A little bit loud, a little bit of cigarette smoke, a little bit of, maybe pot," she said, "but nothing that you wouldn't expect from a bunch of guys."]
