Authorities are again asking for the public’s help in locating a piece of a car mirror connected to the killing of Odin L. Lloyd, an investigation that has led to murder charges against former New England Patriots player Aaron Hernandez and the arrest of two of his alleged accomplices.

Lloyd, 27, of Dorchester, was shot to death June 17 in a North Attleborough industrial park. Bristol District Attorney C. Samuel Sutter’s office alleges that Hernandez orchestrated Lloyd’s execution.

Hernandez has pleaded not guilty to all charges and is being held without bail at the Bristol County Jail.

Shortly after Lloyd was murdered — and before Hernandez was identified as a suspect in his killing — authorities appealed to the public for help in locating the piece of mirror. On Monday, with all three men allegedly connected to Lloyd’s death in custody, they renewed that appeal.

“The police are asking for the public’s help in locating the broken drivers side rear view mirror of this Silver/Grey 2013 Nissan Altima,’’ North Attleborough police and Sutter’s office said in a joint appeal Monday.

Prosecutors have alleged that Hernandez and two men went to Lloyd’s home on Fayston Street in Dorchester early in the morning of June 17 and then drove in a rented Nissan Altima down to the industrial park. After Lloyd was murdered, the other three men allegedly drove to Hernandez’s home on Ronald C. Meyer Drive in North Attleborough.

Authorities asked the public to look for the mirror along the route the four men traveled that morning.

“This mirror maybe found in a wooded or secluded area, somewhere close to the route from Fayston Street in Boston down Route [Interstate] 95, to Ronald C. Meyer Drive in North Attleboro,’’ officials wrote.

Hernandez’s alleged accomplice, according to Sutter, was Ernest Wallace, 41, of Miramar, Fla., who is expected to be in Attleboro District Court later this week to face an accessory after murder charge.

Carlos Ortiz, 27, the other person allegedly in the car, has pleaded not guilty to unlawful carrying of a firearm and is currently behind bars pending a dangerousness hearing for July 9.

Neither Ortiz nor Wallace is charged with murdering Lloyd.

The investigation is ongoing, according to Sutter’s office.

On Monday, Bristol County Sheriff Thomas M. Hodgson said Hernandez is “acclimating very well” at the jail. “He does not appear to be nervous.”

Authorities at the jail today reviewed Hernandez’s classification as a prisoner, and gave him some access to common areas in his unit when they are vacant, said Hodgson. Hernandez is not yet permitted to have direct contact with other pretrial detainees, as the famous former professional athlete slowly adjusts to prison life, he said. His status will be reviewed again in a week.

Officers at the prison have reviewed Hernandez’s tattoos for evidence of gang ties, as is customary with incoming prisoners, Hodgson said. He would not reveal what the review found.

Hernandez is also being investigated for a July 2012 double homicide in Boston’s South End in which two men died in a drive-by shooting, law enforcement officials have told the Globe.

And he is being sued in federal court in Florida by a Connecticut man who claims Hernandez shot him in the face in February after an argument at a Miami strip club. Hernandez had not yet filed a response to the lawsuit today.

In related news, police in Bristol, Conn., confirmed today that they have assisted Massachusetts investigators in executing three search warrants in the various investigations of Hernandez.

Police assisted in the search of a home at 114 Lake Ave., as well as the search and seizure of a silver Chrysler 300 that believe to be linked to Lloyd’s murder in North Attleborough, said Bristol Police Lieutenant Kevin Morrell.

The department also assisted with a search warrant and vehicle seizure at the behest of Boston police. That search also occurred at 114 Lake, and involved seizing a silver Toyota SUV, he said.

The Globe has previously reported that police believe that the Toyota is linked to the July 2012 double slaying in Boston.

As of Tuesday, Massachusetts law enforcement officials had not requested assistance with any other search warrants in Bristol. However, Morrell said, cooperation remains robust between Bristol police and Massachusetts investigators.
