Three Charged in Hannibal Convenience Store Killing

Three more people have been charged with second-degree murder in the fatal shooting of an eastern Missouri convenience store clerk.

The Hannibal Courier Post reports that 27-year-old Cuda Dodd and 23-year-old Amanda Lehenbauer were served with warrants Monday while imprisoned on other charges. On Tuesday, 26-year-old Krystal Tressler was arrested at her work. No attorney is listed for Tressler in online court records.

Two other people, Michael Studer and Gary Wiltermood, pleaded guilty earlier this year in the October 2013 killing of 61-year-old Adrienne Arnett. She was shot to death at Abel's Quik Shop, just west of Hannibal.

Wiltermood told police that the three new defendants were present when the plan was hatched to rob the store to get money for drugs.
