Mark Fellows, Lee Newell, and David Taylor got whole-life terms for stabbing Kyle Bevan 25 times inside HMP Wakefield.

Even in the darkest corners of prison, there is a brutal code. When three men decided to play judge and killer, they sealed their own fates forever.

WHAT HAPPENED

Three British inmates stormed the cell of Kyle Bevan at HMP Wakefield. Bevan was serving time for killing his two-year-old stepdaughter. Within four and a half minutes, the men stabbed him to death.

The attackers used homemade weapons. One weapon was made from metal taken from a television set. After the attack, they put Bevan's body back in his bed to make him look asleep.

Guards found Bevan dead during a morning roll call. A judge has now sentenced Mark Fellows, Lee Newell, and David Taylor to life with no chance of release.

What the money/evidence shows

• 25 stab wounds: The number of cuts and wounds found on Kyle Bevan's body.
• 4.5 minutes: The exact time the three men spent inside Bevan's cell.
• 2 inmates: Fellows and Newell were already serving life terms with no parole before this attack.
• 1 metal weapon: A sharp tool made from a part taken out of a television set.
• 75 prisoners: The number of people in England and Wales serving this ultimate life sentence.

THE BIGGER QUESTION

Who keeps us safe from the people we lock away? When men who already have life sentences commit murder inside, it shows the limits of our prison system.

Can we ever truly secure a prison when inmates can make deadly weapons out of simple room items? We must ask if our highest-security prisons are failing their basic job.

THE OTHER SIDE

The attackers did not deny the act, and they seemed to celebrate after the deed was done. Some might argue that Bevan deserved his fate because of his awful crime against a child. Yet, the law does not allow prisoners to hand out their own death sentences, and the camera footage made any defense impossible.

WHAT HAPPENS NOW

These three men will now spend the rest of their days in high-security cells with no hope of release. For the family of the young girl Bevan killed, this news may bring a strange sense of closure, but it does not bring her back.

Prisons across the UK will likely face new checks on what items inmates can keep in their cells. Security teams will have to search closer for makeshift weapons.

WHAT WE STILL DON'T KNOW

How did the inmates get the metal from the television without guards noticing?

• Why was Bevan left alone in a cell where three violent men could reach him so easily?
• Where is the body of Alisha Apostoloff-Boyarin, whom David Taylor killed but refused to help find?
