A Levering man turned himself in Monday morning on charges in connection to the Kopenkoskey murder case.
John Ernst, 59, is facing a seven count felony warrant that the Sheriff said are in connection to the October 2012 murder of Lyle Kopenkoskey.
Investigators learned through Kopenkoskey's wife, Carol, that Ernst helped her in getting rid of the gun used in the murder.
Ernst is facing one count of accessory after the fact to a felony for his part in that, but is also being charged with six counts of perjury stemming from a Prosecutor's investigative subpoena in August.
According to the Emmet County Sheriff, Ernst is alleged to have given investigators false information under oath.
Each count of perjury is a felony carrying up to life in prison. The accessory charge is up to a five-year felony.
Ernst's bond was set at $100,000.
Lyle Kopenkoskey was found dead on October 2 on Kiebel Road in Emmet County.
Initial police reports show that that during searches of the Kopenkoskey home, deputies found an empty .38 caliber pistol case. Forensic experts believe the five bullets that killed Lyle Kopenkoskey may have come from a .38 caliber gun.
Investigators also found numerous books on committing murder and cleaning up crime scenes in Carol Kopenkoskey's possession.
Initial interviews also revealed that it was likely that Carol Kopenkoskey was having an affair with a business partner.
Carol Kopenkoskey pled guilty to second degree murder, admitting she shot her husband five times before throwing the gun off the Mackinac Bridge. As a part of the plea deal, she agreed to testify against any co-defendants.
