HATTIESBURG, Miss. (AP) — Family and friends will say goodbye today to a 6-year-old autistic boy who was killed while police in Louisiana were chasing his father.

A funeral for Jeremy Mardis will be held at a church in Hattiesburg, Mississippi.

Authorities say Jeremy died last Tuesday in Marksville, Louisiana, after city marshals fired into a vehicle driven by his father, Chris Few. Few was seriously wounded.

Three days after the boy was killed and his father wounded, authorities arrested two of the four officers involved in the shooting, the head of the state police announced Friday.

Col. Mike Edmonson gave few details of what exactly unfolded Tuesday night that led authorities to arrest the officers. But he made his disgust clear.

Speaking of the body camera footage that was recovered from the officers, he said: "It is the most disturbing thing I've seen, and I will leave it at that."

Edmonson said Friday that the two officers are being booked on charges of second-degree murder and attempted second-degree murder in the shooting. Edmonson identified the two officers as Norris Greenhouse Jr. and Derrick Stafford. Both were working secondary jobs in Marksville as marshals when the shooting happened, Edmonson said.

Edmonson said earlier that no weapon was found in the vehicle.
