PIERRE, S.D. – South Dakota Attorney General Marty Jackley announces that a Centerville man has been sentenced to three consecutive sentences of life in prison without the possibility of parole after earlier being found guilty for a 2024 triple homicide that occurred in Centerville, SD.
Jay Ostrem, 65, was sentenced Thursday in Turner County Circuit Court which was held in the McCook County Courthouse in Salem. He had been found guilty of three counts of First-Degree Murder by a Turner County Jury in March.
“This sentence provides justice for the families of the three victims who we keep in thoughts,” said Attorney General Jackley. “These complex cases could not have been successful without the tireless efforts of law enforcement officers and prosecutors.”
Victims in the shooting death were identified as Paul Wyland Frankus, 26; Zachary Frankus, 21; and Timothy Richmond, 35. The incident was reported near 10 p.m. on May 27, 2024, at a residence in Centerville.
South Dakota’s Division of Criminal Investigation (DCI) led the investigation. The case was prosecuted by the South Dakota Attorney General’s Office and the Turner County State’s Attorney’s Office.
