The South Australian policing family is in mourning after an officer was killed in a shootout - the state's first police death in the line of duty in more than 20 years.
Brevet Sergeant Jason Doig and colleagues Michael Hutchinson and Rebekah Cass were on a "routine" assignment to a rural property in Senior near the Victorian border about 11.20pm on Thursday to investigate an incident involving the use of a firearm and an animal.
