Louisiana police arrested two officers over the fatal shooting of a 6-year-old autistic boy in the central town of Marksville, the head of the state police announced Friday. The incident occurred Tuesday after officers fired at a vehicle in what they called a pursuit.

The boy, Jeremy Davis Mardis, was killed and his father, Chris Few, was wounded in the incident. Col. Mike Edmonson, in a late-night press conference, announced the arrests, the Associated Press reported, adding that they were booked on charges of second-degree murder and attempted second-degree murder in the shooting.

"It is the most disturbing thing I've seen, and I will leave it at that," Edmonson reportedly said, while talking about the body camera footage that was recovered from the officers.

The two officers have been identified as Norris Greenhouse Jr. and Derrick Stafford, who were working in Marksville as marshals. The mugshots of the two officers were released by the state police.

Edmonson reportedly said that there was no exchange of gunfire during the incident Tuesday, and no gun was found in Few's vehicle.

Authorities reportedly said that two other officers were believed to be involved in the incident. An investigation is underway into the shooting as authorities analyze the four guns seized from those involved.
