KENNEBEC, S.D. (AP) — A grand jury in Lyman County has indicted a 27-year-old woman on one count of second-degree murder.

Attorney General Marty Jackley says Whitney Turney, of Oacoma, was indicted Wednesday. She's accused of killing Calvin Shields on Sept. 4. Authorities say Shields was stabbed to death.

Jackley says 27-year-old Dayna Wells was also indicted on one count of accessory to a crime. Authorities allege Wells assisted Turney in her attempt to conceal, destroy or alter evidence.

Turney was arrested on the evening of Sept. 8. If convicted, she faces a mandatory life sentence in prison.

Wells faces up to five years in prison.

Turney's attorney did not immediately return a call seeking comment. An attorney is not listed for Wells.
