A semi-retired businessman has been charged for allegedly trying to murder a woman by spiking her tea with insecticide.

Stephan Wagner, 61, was arrested at his home in St Andrews, south-west Sydney, at 11.35am on Tuesday after allegedly poisoning a 66-year-old woman in a domestic violence incident.

An investigation was launched last month after the woman became seriously ill after drinking tea allegedly prepared by a man she knew.

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.

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.
