The police are looking into how he died.

A group that checks on deaths in prison is also looking into it.

The killer, Thomas Haigh, was given a life sentence for the murders.

The two men he killed were found dead after another man told the police what happened.

This other man, Ross Stone, was given a five-year sentence for burning and burying the bodies.

Haigh and Stone owed the two men a lot of money for drugs.

The judge said Haigh was a young man who thought he was tough but got in over his head.

The judge also said that just because the two men were bad, it didn't mean they should be killed.

Haigh thought he was a big shot in the criminal world.

But the judge said Haigh's behavior was unpredictable and not suited for that life.

The two men Haigh killed were part of a gang that controlled the drug trade in Liverpool.

Haigh didn't show any emotion when the judge talked about the case.

The judge said Haigh shot the two men by himself.

Haigh left Stone to clean up the mess.

The judge wasn't sure why Haigh did it, but he knew Haigh was the one who pulled the trigger.

Haigh turned himself in to the police after the killings.

Stone said Haigh had talked about killing the two men before it happened.

One of the men Haigh killed was from Plymouth and sold drugs there.

The families of the two men reported them missing after they didn't come home.

The police found the bodies after they arrested Stone for growing marijuana.

Stone told the police where the bodies were hidden.

Stone said he was scared of the two men's friends, so he buried the bodies instead of telling the police.

Haigh tried to appeal his conviction, but it didn't work.

Another prisoner said Stone had confessed to the crime, but the judges didn't believe him.

The judges said this prisoner was a liar.

They didn't think the story about Stone confessing was true.

The judges didn't change Haigh's conviction, but they did reduce his sentence a little bit.
