The Windsor Police Service Board has doubled the reward for information leading to information to solve the murders of Marlene and Jason Sweet.
The reward is now $40,000.
Marlene and her seven-year-old son Jason were found badly decomposed around two weeks after their murder in 1982.
There's also a $40,000 reward for information in the murders of Dee Dee Williamson and Xavier Rucker.
On February 27, 2003, Williamson and Rucker were found in their house on Tilston Drive. Williamson had been beaten to death and was found in the basement. Rucker was found in a main floor bathroom. His cause of death has never been disclosed.
The board has also extended the reward period for four other cold cases in the city.
The board is offering $20,000 for any information that leads to the identification, arrest and charge of suspects in the murders of Kirk Knight (1980), Geraldine Butterfield (2019), and Jerome Allen (2018).
All of the rewards were set to expire on December 31, 2023.
