SPOKANE, Wash. - Spokane Police announced Thursday afternoon they have arrested three people on 1st Degree Murder charges in connection to the murder of Mark Broadwater. Broadwater's body was found in the Fernan Lake in Kootenai County earlier this month. Broadwater went missing back in April 2013. 

The three people arrested are: 

  • 47-year-old Jeffery B. Sankey
  • 40-year-old Judy L. Diamond
  • 44-year-old Peter E. O’Brien
A look into Sankey's 22 year criminal history revealed 12 felony convictions that included Burglary, Possession of a Firearm, Assault, Possession of a Controlled Substance and Possession Without a Prescription. 

Judy Diamond does not have any felony convictions in the state of Washington. Her first court appearance is pictured on the right.

Peter E. O'Brien's criminal history dates back to 1989 with eight felony convictions, including Burglary, Theft of a Firearm, Possession of Stolen Property, and Possession of a Controlled Substance with Intent to Deliver. He also has 19  gross misdemeanors that include Vehicle Prowling, Assault, and Exhibiting or Displaying a Weapon with Intent to Intimidate. KHQ's Dylan Wohlenhaus spoke with O'Brien Thursday morning and O'Brien said he had nothing to do with the murder and hadn't talked to Sankey or Diamond in a year. Broadwater has been missing since April 2013. 

However, police say it was an interview they had with O'Brien while he was in jail on unrelated charges that first led them to believe all three suspects were involved in Broadwater's disappearance. Detectives believe Broadwater knew all three suspect and think his death happened during a drug-related robbery. 

Police say there are no outstanding suspects in the case.
