Two Louisiana police officers charged with murder after shooting dead a six-year-old autistic boy were moonlighting for a controversial local marshal agency, it has emerged.

Lt. Derrick Stafford, 32, and Norris Greenhouse Jr., 23, a reserve officer, were arrested Friday night by the Louisiana State Police after the shooting death of Jeremy Mardis and the wounding of his unarmed father, Chris Few, in the central Louisiana town of Marksville on Tuesday.

It has since been revealed, the pair - along with another officer at the scene - were moonlighting as marshals who work for the city courts and serve warrants, carry firearms and have police powers.

The local agency is run by school bus driver city marshal Floyd Voinche.

Mayor John Lemoine, says Voinche, who has served as marshal for the past 12 years and was recently re-elected unopposed, has recently begun overstepping his authority.

The Advocate reports Voinche lacks basic law enforcement certification.

Lemoine told the newspaper that Voinche has been obtaining squad cars to issue tickets which is not a role they would normally undertake so he contacted the Attorney General’s Office - he is awaiting a response.

'I don't know why he felt the need to start patrolling in city limits,' Lemoine said to the Guardian. 'It makes no sense to me.'

Jeremy Mardis, a first-grader from the town of Effie, was shot five times in the head and torso when deputy marshals opened fire on his father's fleeing car.

Coroner Dr L. J. Mayeux said it was likely that Jeremy was caught 'in the line of fire' as the marshals shot at the driver's side, with the boy on the passenger's side of the car.

It's still unclear what led police to pursue Few and what triggered the shooting.

Col. Mike Edmonson said that there was no weapon found in the SUV or any indication that shots were fired from that vehicle.

The parish coroner said earlier this week that the officers were serving a warrant on Few when he fled, but Edmonson later said he had no information about a warrant.

Records in both Marksville city court and the area district court show several traffic violations and a recent DWI conviction but no outstanding warrants or ongoing criminal cases, reports the The Advocate.

Edmonson said the Greenhouse and Stafford were booked on charges of second-degree murder and attempted second-degree murder.

In the late night press conference he said: 'Let's make tonight about Jeremy Mardis.

'That little boy was buckled in the front seat of that vehicle and that is how he died. He didn't deserve to die like that.'

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.'

'The initial statement to my investigators was that the vehicle was backing up, they feared for their lives and they started firing,' Edmonson told CBS News.

'I think the longer it takes for these officers to come forward and give us information, it's more concerning,' Edmonson told CBS News Friday morning.

Chris Few and his son Jeremy Mardis were shot on Tuesday night in Marksville by the cops who were believed to be trying to serve the driver a warrant

Few's fiancee Megan Dixon (pictured) said: 'No, he didn't have a gun because I'm the reason why this all started. And I know what happened'

Two other officers, Lt. Jason Brouillette and Sgt. Kenneth Parnell, were involved in the incident.

When Edmonson was asked whether he anticipated any more arrests, he said: 'We'll see where it takes us.'

It has since emerged that in October, 2011, Lt. Derrick Stafford was indicted by a Rapides Parish grand jury on two counts of aggravated rape, reports KATC - the station says it is waiting for records to see exactly how it was resolved.

The station also reported he has five pending civil lawsuits involving him in Avoyelles Parish and Norris Greenhouse Jr. was also named in several of the suits.

One of the cases alleges that while arresting a woman involves Stafford Tasered her without warning while she was cuffed in the back of the car.

Another case claims while breaking up a fight between two girls, Stafford allegedly pulled a 15-year-old girls' arms behind her back and apparently broke her arm.

KATC reports the pair are named in a July lawsuit filed in federal court along with five other Marksville police officers regarding an arrest of a man at a festival which ended up with him being Tasered.

Few's fiancee Megan Dixon told the Guardian that earlier in the evening she had argued with him at TJ's pool hall and she left.

Few went to pick up his son who had been at a relative's house.

A short while later, Few pulled up next to Dixon at a stop light and asked her to come home with him.

She said she declined because she was 'stubborn.'

The coroner said Few, left, reached a dead end and was backing into the marshals when they fired and the boy, right, was 'caught in the line of fire' and killed

She said as she pulled away she saw two marshals' cars approaching from behind with their lights flashing.

Megan said she saw Few was pointing at his son's head, showing that he was in the car and he wasn't sure what to do.

She said her fiance was not comfortable because he had previously had a conflict with one of the marshals. She did not identify which marshal.

'No, he didn't have a gun because I'm the reason why this all started,' she said reports Towntalk.

'And I know what happened.'

Few's 57-year-old stepfather, Morris German, has accused the marshals of indiscriminately opening fire on the vehicle.

German said Few was heavily sedated, unable to talk and has bullet fragments lodged in his brain and lung.

He described Few as a loving father and added the man's son 'was his whole life.'

Investigators said that the marshals were shooting into the driver side, and the six-year-old, pictured, was on the passenger side

German added that the 6-year-old had been diagnosed with autism, describing him as a delightful child who 'loved everything, everybody.' German said the boy had no siblings and the family had recently moved to Marksville from Hattiesburg, Mississippi.

'I know a 6-year-old should not have been shot,' German said.

On Wednesday Blaine Dauzat, the Avoyelles superintendent of schools, said Mardis moved to the school district from Mississippi at the end of his kindergarten year last April.

'We are definitely all shaken up,' he said. 'It's been a tough day at work for all of us.'
