A $250 thousand reward is still in place for those with information on the disappearance of Robert Grayson and Derek Van Der Poel who went missing in 1993. Rosedale man, Russell Williams, had been charged with two counts of murder but was found dead in his Jail cell on Tuesday morning. Police say they're treating the 51 year old's death as not suspicious. Mr Grayson and Mr Van Der Poel's bodies are yet to be found and the reward remains.
