Many offenders come out reformed from the rehabilitation centres. 

However, some struggle to be accepted by society after release, which pushes them into despair. 

One such person facing this predicament is Windhoek's Katutura resident, Petrus Mayunda (53), who did stints as an inmate at the Windhoek Correctional Facility in 2017. 

His offence was dealing in drugs, but he was released later.

Quinton Pieters, who was sentenced to 163 years in prison for various crimes, remains hopeful that one day he will reclaim his freedom.

The nbc News team paid a visit to the inmate serving Namibia's longest sentence at the Evaristus Shikongo Correctional Facility outside Tsumeb.

Quinton Pieters, born in Keetmanshoop, says that as part of a gang, he has been in and out of jail since 1993 for committing different crimes.
