Police are appealing for information about the gangland execution of a father and son in Sydney's west last year.
Salim Hamzy, 18, and his father Toufik Hamzy, 64, were shot dead as they sat parked in a ute at Guildford at 9am on October 20.
Strike Force Ormerod was established to investigate the killings amid speculation the men were victims of the tit-for-tat gangland war between the Hamzy and Alameddine crime networks in their battle over drugs.
