A Shingletown man's confession to a Shasta County murder in 1993 led to the arrest of two other suspects, siblings Shanna and Curtis Culver of Red Bluff.
For the first time, the man who confessed, Brian Hawkins and Curtis Culver, appeared in court.
Shanna is being arraigned as a minor since she was 17 at the time.
The Culver siblings are accused of killing 19-year-old Frank McAlister in 1993.
The Culver's mother was inside the courtroom listening as her son spoke to the judge.
Once outside, the Culver's mother told Action News Now she believes her children are innocent and that Curtis must have been pressured to admit to murdering someone.
"What I believed happened was they said you say this we're going to let your sister go and he would do anything to save his sister," said Marcia Keel, the mother of Shanna and Curtis Culver.
The mother adds she remembers that day perfectly because they were celebrating Shanna's 17th birthday.
The Culvers and Brian Hawkins, whose confession brought about the arrests, are due back in court on Wednesday.
