One of the police officers investigated over photographs connected with the death of Elijah McClain in Colorado has resigned, Aurora police said Thursday.

In a tweet, the department said that Jaron Jones was one of the employees depicted in the photos, which were taken sometime after McClain's death last summer. The department has not released details about what they show or said how many officers were being investigated, only that the photographs were taken near where three white officers stopped the Black man as he walked down the street and put him in a chokehold.

Jones, who has been with the department for over three years, could not be immediately located for comment.

On Monday, interim Chief Vanessa Wilson announced the investigation into the photos and said that multiple officers had been taken off enforcement duties because of the probe.

Multiple suburban Denver police officers have been placed on paid administrative leave amid an investigation into photos of them related to the case of a Black man who died last summer after he was stopped and restrained, police said Monday, June 29. Wilson said in a statement that the suspended officers were "depicted in photographs near the site where Elijah McClain died." But her statement did not provide more details about what the images show. (Philip B. Poston/The Aurora Sentinel via AP, File)

The Colorado U.S. Attorney's Office, the U.S. Justice Department's Civil Rights Division and the FBI are also looking into the photos to see if they should launch a civil rights investigation into what happened.

After Aurora's internal photo investigation was announced, the federal agencies also announced that they have been reviewing McClain's death since last year to determine if a civil rights investigation is warranted into that as well. The Justice Department usually does not comment on investigations until they are complete, but the announcement noted that "there are specific cases in which doing so is warranted if such information is in the best interest of the public and public safety."

Three officers stopped McClain as he walked down the street last August after a 911 call reported him as suspicious. Police placed him in a chokehold, and paramedics administered 500 milligrams of sedative to calm him down. The 23-year-old suffered cardiac arrest, was declared brain dead and later taken off life support.

McClain's death generated renewed attention after the death of George Floyd stirred worldwide protests over racial injustice and police brutality. Floyd died on May 25 after a white Minneapolis police officer pressed his knee into the handcuffed Black man's neck for nearly eight minutes.
