A substantial $500,000 reward has been announced for crucial information that could help solve the mystery surrounding the 1995 disappearance and suspected murder of Tammy Dyson, who was known to work in Fortitude Valley.



Tammy Lisa Dyson, who also went by the name Tamela Menzies, was a 23-year-old mother of two from Victoria who had established her life in Queensland. She had moved to Brisbane in 1988, where she and her sister Olivia found employment in the nightlife of Fortitude Valley, particularly at Red Garter. 

Under the nickname “Pebbles,” Tammy was associated with individuals involved in illicit activities known to local police.
