Looking for family

Authorities at Pollsmoor Prison need help finding the family of a recently deceased inmate.
Offender Stephen Neil, registration number 216509162 died of natural causes in Pollsmoor Remand Detention Facility. He did not provide Pollsmoor management team with a fixed address or any details of his next of kin during the admission stage. Fellow prisoners only mention the name of his sister, either Kathleen or Kathline but they have no idea where to find her.
Pollsmoor staff have exhausted all avenues to locate any relatives of the deceased and are asking the community for help. Anyone with information should contact Pollsmoor Records Section at 021 700 7811.
