Mr Johnson suffered a fatal stab wound to his chest, and a slash wound to his throat, before prison staff were able to intervene and separate him from his assailant.
Mr Johnson was subjected to the unprovoked assault after a minor disagreement earlier about a TV remote control.
Tragically, the victim - who was serving a four year sentence for theft - was scheduled to be released in just four weeks having completed his sentence at Cork Prison.
Mr Johnson, who was from Bandon in west Cork, had told prison officials he planned to rebuild his life having received help for a serious gambling problem while in custody.
The attack was immediately stopped by Cork Prison staff but not before Mr Johnson had sustained critical injuries.
No prison officers were injured.

The entire incident lasted only a matter of seconds.
Both prisoners were working near the kitchens as ‘trustee inmates’.
Emergency medical treatment was provided for the injured inmate at the scene.
However, he died before he could be transferred by ambulance to Cork University Hospital (CUH).
Mr Johnson suffered from a significant chest injury as well as major blood loss.
An investigation is now underway into the incident by Gardai, the Irish Prison Service and the Irish Prison Inspectorate.
Forensic experts conducted a detailed technical examination of the scene.
