The 2003 killing of a Camano Island woman is now considered solved - however, the suspect who confessed to the crime won't see a trial. On Thursday evening, the Island County Sheriff's Office announced that they closed their investigation into the homicide of 39-year-old Tammy Mattson, who was found dead 21 years ago. Prosecutors and police said they are confident in the identity of the killer, however, 69-year-old Carl Schlobom will not be charged. KING 5 is naming Schlobom because police said his confession included information only the killer would know, and investigators are "certain" Schlobom killed Mattson. Greg Banks, the Island County prosecuting attorney, told KING 5 that while Schlobom hadn't been found guilty by plea or a jury, "I can say that I am as confident as I have been in any other case, that I've tried to conviction, that he is the murderer. I talked with him on the phone, and I have no doubts." READ MORE: https://www.king5.com/article/news/crime/camano-island-cold-case-murder-solved/281-72440bd9-dff8-48f5-9c27-3acb6be7d50f
