Do you know who murdered Brian Underwood?

Posted on 24/07/2019

The 25th of July 2019  marks the 28-year anniversary into the unsolved poisoning murder of Brian Underwood.
At about 4pm on Thursday, 25 July 1991, the then 46-year old sales manager and father of two collapsed at his workplace in Carrington Street in the city.
He was treated at the scene and conveyed to the Royal Adelaide Hospital in a critical condition.
He died later that evening about 6.30pm and a post-mortem revealed a lethal dose of potassium cyanide.
Police subsequently found a forged receipt for potassium cyanide in the possession of a woman who was formerly employed at Mr Underwood’s workplace.
She remains a person of interest in the investigation, with testing having determined that Brian was targeted by someone who had access to his workplace.
A reward up to $200,000 is on offer to anyone who provides information and assistance that leads to the conviction of the person or people responsible for his death.
No one has ever been charged over his death.
Anyone with information should call Crime Stoppers on 1800 333 000 or report online at
