Businessman Stephan Wagner accused of poisoning his wife’s tea in Sydney
EXCLUSIVE
A semi-retired businessman has been charged after allegedly trying to kill his wife for more than 18 months by spiking her tea with Antrid.
Stephan Wagner, 61, was arrested at his home in St Andrews, in Sydney’s south-west, at 11.35am on Tuesday after allegedly poisoning 66-year-old Glenda Wagner in a domestic violence incident.
An investigation was launched last month after she became seriously ill after drinking tea he allegedly prepared.
Police now allege Wagner began poisoning her with the Borax-laced Antrid on Boxing Day 2022 until she was admitted to hospital at 6:23 pm on September 16, 2024.
Daily Mail Australia can reveal Wagner held several management positions at major companies before entering semi-retirement in March 2023.
According to his LinkedIn profile, he worked for various government departments in the 1990s, including as an engineer for scientific research agency CSIRO and as a communications manager for the military.
He also held management positions for Optus, UNSW and Nokia in the same decade.
Wagner went on to hold various positions at other major companies, including Telstra and Cisco, before taking on the role of AusIndustry Regional Manager for Western Sydney in 2013 until retiring last year.
His extensive CV also states that he worked as a part-time lecturer at the University of Western Sydney between 2013 and 2015, teaching marketing principles.

Reports online indicate that he is a semi-retired businessman and fitness fanatic
According to his profile bio, he is currently enjoying semi-retirement while still “enabling business success.”
Photos posted online show Wagner, who is originally from Melbourne, is a fitness enthusiast who enjoys running marathons.
Last week he revealed he was planning to take on a month-long fitness challenge to raise money for the Royal Flying Doctor Service.
“Australia is a large country and for those living in rural and remote areas, access to immediate care is not a guarantee. For some communities, the nearest hospital is eight hours away,” he wrote.
‘In October I will be taking on a month-long fitness challenge to give more people access to the care they need. By continuing, I hope to raise as much as I can for the Royal Flying Doctor Service (RFDS).”
In June last year, he also took part in a push-up challenge to raise awareness for suicide prevention.
Wagner will be taken from his home by the police on Tuesday
Police also seized a bottle of insecticide from the house, which has been sent for forensic examination.
Property records show Wagner lived in the home where he was arrested for more than 29 years.
He was taken to Campbelltown Police Station and charged with three offenses of domestic violence: taking poison with intent to murder, using poison to endanger life, and using poison to cause grievous bodily harm to bring.
Police also seized a bottle of insecticide from the house, which has been sent for forensic examination.
Wagner was escorted from his home by police in handcuffs, wearing cargo pants, a polo shirt and black runners.
After spending the night in custody, Wagner appeared in Campbelltown Local Court via video link on Wednesday.
Dressed in a red sweater, Wagner appeared stoic as he sat quietly and spoke only to confirm his name to magistrate Clare Farnan.
Wagner did not apply for bail and his lawyer asked for the case to be postponed.
He is due to appear in the same court on December 4.
