More details have emerged regarding the final hours of Army Staff Sgt. Logan Melgar, 34, who died from asphyxiation in a home he shared with two Seal Team 6 members in Bamako, Mali.

For their involvement in the incident on June 4, 2017, two SEALs and two Marines were initially charged with felony murder, involuntary manslaughter, obstruction of justice and hazing.

A feud developed between Melgar and the four other servicemen, leading them to plan a revenge hazing, according to released statements

Now new information has emerged from a stipulation facts by Maxwell, and obtained by The Washington Post, which expose a sinister plot intended to embarrass Melgar after a night the four of others went drinking.

The group planned on breaking into Melgar's bedroom with a sledgehammer, choking him until he fell unconscious and tie him up with duct-tape, the report says.

Then a Malian security guard would sexually assault him while a British man who had befriended the Americans, would film it.

A longstanding feud had gone on between the SEALs and Melgar, after he accused them of bringing prostitutes back to their safe house and taking cash from a fund intended to pay local informants, according to the Daily Beast.

In a message handed over to authorities, he told his wife Michelle: 'I freaking hate them.'

The SEALs had disliked Melgar for engaging in 'frat-like' behavior and had at times caused them to be 'uninvited' from U.S. Embassy events, documents revealed.

They had become so angered by Melgar that they banned him and another Special Forces solider from their operations center.

On the night of his death, the SEALs were furious after he ditched them for a party at the French Embassy.

Hours later, one of the soldiers claimed that Melgar boasted about making the right decision as it was a 'high class' event, enraging them further.

More information has just been released about Melgar, who was believed to have accused two of the SEALs of bringing prostitutes to the safe house and skimming money from a fund reserved for public informants

Meanwhile the four had hatched a plan while out on a heavy night drinking whiskey and beer at Appaloosa bar, before going onto a nightclub called Byblos - according to documents.

Back at the house, at around 5am they decided to 'surprise him' with the attack Matthews stated in his stipulation of the facts.

It was then that former professional mixed-martial-arts fighter DeDolph, jumped on Melgar and put him in a chokehold on his bed.

Matthews grabbed his legs while the two Marines duct-taped his legs, upon trying to bind his hands together they noticed he wasn't breathing.

The troops began performing CPR, retrieved a defibrillator and tried to re-open his airways with an emergency procedure on his throat.

Deciding that there was no time for an ambulance they rushed him to a clinic, where he was later pronounced dead.

Maxwell's testimony sheds further light on the night's events, with the plan to film a sexual assault upon Melgar not previously known.

It was revealed that Maxwell had been on a riverboat cruise with Melgar and other friends the same week of the attack.

The civil defense attorney for Maxwell, Brian Bouffard, said that his client intends to plead guilty to charges including negligent homicide at a court martial at Naval Station Norfolk in Virginia.

Bouffard told The Washington Post: 'They committed a prank on Melgar.

'It was a stupid prank, and it was not the kind of prank you or I would want pulled on us. It went bad.

'Maxwell is eager to accept responsibility for his role in it.'

Bouffard has declined to comment on the stipulation of the fact submitted by Maxwell.

It could carry up to three years in prison, dishonorable discharge and demotion, as well as further time added for other charges.

Matthews pleading guilty to lesser charges on May 16 and was sentenced to one year in military prison by Navy Capt. Michael J. Luken.

Prosecutors agreed to drop the murder charge in exchange for testifying against the other SEAL and two Marines.

He pleaded guilty to conspiracy, unlawful entry, hazing, obstruction of justice and assault with battery.

Luken also demoted Matthews to special operator second class and bad-conduct discharge.

Matthews said: 'I've carried the weight of Staff Sgt. Melgar's death every minute of every day since that night in Mali.

Grover Baxley, Matthews' attorney, described Melgar's death as an 'unforeseen accident' and said it 'dramatically impacted the lives of everyone involved.'

He said that Matthews took 'full responsibility for his role' in the incident and enabled the Navy to resolve the case.

At the time of Matthews's sentencing Melgar's mother, Nitza Melgar, told called him 'a disgrace to your Purple Heart.'

He had received the award among other medals after suffering injuries in Afghanistan.

Melgar's wife, Michelle, in her victim impact statement was 'grateful' to Matthews for 'finally coming forward'.

She said: 'This has been a nightmare that I would never wish on anyone.'

Michelle added that she did not care about the length of his sentence, so long as he is never in a position to commit a similar act again.

'I have hurt enough for everyone, and I’m so very sorry that your family will now have to hurt in a similar way as I have.

'I sincerely hope you make better choices when your day of freedom comes.'

DeDolph and Madera-Rodriguez have not entered pleas and still face court martial.

The Attorney for DeDolph, Philip Stackhouse has rejected the details supplied by Matthews and Maxwell.

In a statement, Stackhouse said: 'We absolutely deny there was any intent to sexually assault Melgar.'
