Brevet Sergeant Doig was killed and Sergeant Michael Hutchinson wounded after they were allegedly shot by Jaydn Stimson, 26, at a rural property in Senior, near the Victorian border, on November 16.

Stimson remains in hospital under police guard and has been charged with murder and attempted murder.

The police investigation is ongoing.

Acting police commissioner Linda Williams today remembered Sgt Doig as a police officer who had an unwavering dedication to his community and a kind and empathetic nature.

“What I’ve learned is that Jason was regarded by many as the quintessential bloke who embodies what it means to be a country police officer,” Williams told mourners.

“The universal description of Jason is that he was kind, caring, generous and unique.”

Sgt Doig joined the police academy at the age of 19 in 1989 and served the past 12 years as the officer in charge of the Lucindale police station.

Originally from Victoria, Sgt Doig had a long affinity for country policing and was known for his willingness to back up and cover his colleagues, the acting commissioner said.

“It was this team-first attitude and willingness to travel to assist members that saw him attend the incident in Senior on that fateful night in November,” Williams said.

A police chaplain said Sgt Doig was remembered as a legendary country cop.

The slain police officer’s brother Brett said that at 53, Sgt Doig “was not done yet” and he and his family felt robbed.

Sgt Doig is survived by his mother Faye, stepfather Rob, brothers Brett and Greg, sister-in-law Beth and nephew Liam. His father Ian had died before the shooting.

“(Jason) certainly lived a life to the full,” Brett told mourners.

“He embraced it (and) never went backed away from a challenge or a new adventure – in fact, he sought them out.

“We are very blessed to have been brought along with him on his ride.”

SA Premier Peter Malinauskas, ahead of the memorial, announced the state government would donate $100,000 to Women’s Safety Services SA in Sgt Doig’s honour.

The police officer’s family requested mourners also donate to the organisation in lieu of flowers.

Monday’s event was the second public memorial in as many weeks, after more than 1000 people gathered to mourn the loss of SA Police Commissioner Grant Stevens’ son on Thursday.

Charlie Stevens died on November 18 after sustaining irreversible brain injuries in an alleged hit-and-run incident at Goolwa Beach.

Landmarks were lit up in blue in memory of Sgt Doig and in support of the police family more broadly last week.

Blue lights shone on buildings across Adelaide, including police headquarters, Adelaide Oval, parliament house and Adelaide Town Hall.

Williams previously said both Sgt Hutchinson and Constable Rebekah Cass, who was also at the scene of the shooting but was uninjured, were home recovering from the incident.

“(They) placed themselves at great personal risk to render first aid to Brevet Sergeant Doig and handcuff the accused under what was an incredibly confronting and distressing incident,” Williams said.

“It is now evident to me that Sergeant Hutchinson and Constable Cass performed their duties on the night with courage and bravery.”

Sgt Doig’s live-streamed funeral service began at 11am at the Adelaide Convention Centre.
