Nicole Walker pleaded guilty Monday for her role in the murder of Brian Carson earlier this year.
Walker was facing accessory charges for Carson's murder.
The County Attorney describes that charge as helping the suspect *after* the crime was committed.
Prosecutors say 19-year old Ryan Carson killed his father in their family home-the coroner determined blunt force trauma was the cause of death.
Then 19-year old Walker and 22-year old Jeffrey Hill helped Carson try to get rid of the body.
Investigators say Walker had a relationship with both Ryan and Brian Carson.
Eight different suspects are facing charges in this crime.
