The mother of a man accused of shooting and killing a South Australian police officer is now facing charges herself.
In November three officers were called to an isolated rural property in the town of Senior, 15 kilometres north of Bordertown, after reports a dog had been shot.
It's there that the officers were confronted by Jaydn Stimson and a shootout occurred. Brevet Sergeant Jason Doig died and Stimson has been charged with murder.

The 26-year-old's mother, Lynette Stimson, is now facing a firearms charge linked to another gun found during the investigation.
"They relate to allegations that she didn't transfer ownership of a firearm following the correct procedure," lawyer Andrew Graham said.
The weapon was found in Jaydn's possession but was still registered in his mother's name. Their lawyer said it was not the one used in the deadly confrontation.

"They both have firearms licences, I can't comment on where the firearm was found or whether it was secured or not, just because I haven't received that information yet," Graham said.
Neither mother nor son was in court today. Jaydn has been in a criminal mental health facility since his release from hospital.
He was recovering from a gunshot wound sustained in the confrontation with Doig and the two other officers, Constable Rebekah Cass and Sergeant Michael Hutchinson.
Hutchinson was also shot and Jaydn is charged with his attempted murder. Cass was not physically injured.
Lynette is said to be struggling with the alleged murder.
"She is obviously very devastated about what has occurred, they come from a small community in the country and it's been extremely upsetting for them, and I know she is very upset by what occurred," Graham said.
Lynette is expected to face court in May.
