Johnson is accused of beating and stabbing Shirley
Marlene was immediately suspected and was found with incriminating evidence. She was arrested only 12 hours after Shirley's body was found.
When she learned the death penalty was on the table, she flung herself off her bunk in an attempt to break her neck but received only cuts and bruises. Her case was scheduled for court this year but documents were filed in February to postpone it due to lack of county resources.
