The parents of the victims of former Parktown Boys' High assistant coach Collan Rex have relayed the emotional turmoil that they endured as the details of what happened to their sons emerged in court."When you then sit in the courtroom and hear the details, that's hectic stuff," an emotional mother said.She said many parents heard what happened for the first time when the trial got under way. "My son, for instance, said: 'Mom I'm not giving you the details. I'm not telling you anything,'" she said.The boys would only talk to the investigating officer and State representatives.Long journey aheadBut she warned that it was not the end of their journey because their goal was always to challenge the school and the Gauteng Department of Education."We still have a long journey ahead of us because this little band of mommies that came on board are absolutely determined that today we only have a partial victory in the sentencing of Collan Rex," she said. "The real victory will come when the school stands up and abolish all forms of initiation, all grade camps, all first team initiation camps, when they fire the teachers that looked the other way when our boys were being abused."Other parents agreed that they didn't just want to see justice prevail, but also wanted to challenge the "systematic abuse that has been happening at Parktown Boys".The parents were speaking after Acting Judge Peet Johnson Rex sentenced Rex to 23 years behind bars - 20 years for sexual assault and three for common assault – on Thursday.Rex initially faced 327 charges. However, he pleaded guilty to 144 counts of sexual assault and 12 counts of common assault.Johnson did not mince his words when he imposed the sentence and described Rex, who recently turned 23 in September, as a "serial sexual offender and sexual bully". Johnson added that the sentence would also send out a message to other predators that sexual offences were taken seriously."Your reign of terror, fortunately for [them], has now ended," Johnson said.Read: Court hears of Parktown Boys assistant coach's difficult upbringingParents said they would now pick up the pieces and move on.After the proceedings, an emotional father said they had not expected the harsh sentence, but were happy that it was "a lot more" than what they had expected.He said they would now focus on their son: "We just want to focus on my son recovering, healing and carrying on; and need to make sure that this thing never happens again.
