The former mayor of a small South Dakota town has been charged in a Memorial Day triple murder.
South Dakota Attorney General Marty Jackley announced Tuesday that Jay Ostrem, 64, of Centerville, has been charged with three counts of first-degree murder in the shooting deaths of three people Monday night.
“There is no further threat to the public,” Jackley said in a statement.
According to a press release from Jackley’s office, the homicide at a Centerville residence was reported around 10 p.m. Monday. The names of the three victims will not be released until their families have been notified.
Ostrem previously served as a city council member and mayor of Centreville, a small town in Turner County with a population of less than 1,000 that was named Community of the Year by the Governor’s Office of Economic Development last month, according to local reports.

A woman who answered the phone at the Turner County Sheriff’s Office said deputies are still on scene but will release photos of Ostrem’s arrest warrant at a later date.
The South Dakota Bureau of Criminal Investigation is investigating the death along with the Centerville Police Department, South Dakota Highway Patrol, Beresford Police Department, Biborg Police Department, Lincoln County Sheriff’s Office, Turner County Sheriff’s Office and the South Dakota Department of Game, Fish and Parks, the attorney general’s office said in a statement.
