Three more people face charges in the death one year ago of Hannibal convenience store clerk Adrienne Arnett.

Hannibal Police say 26-year-old Krystal Tresler was arrested Tuesday at her place of employment and is charged with second degree murder. 27-year-old Cuda Dodd and 23-year-old Amanda Lehenbauer are also charged with second degree murder in Arnett’s death.

Dodd and Lehenbauer are incarcerated in the Missouri Department of Corrections on other charges. Tresler is held in the Marion County Jail. Bond for the three suspects is set at 100-thousand dollars cash only.

Gary Wiltermood and Michael Studer both plead guilty to second degree murder charges last summer for their roles in the death of Arnett.
