Flowers relates that detectives noticed Patti had been stabbed in the heart and the knife came from a butcher's block she had in her home. Ashley is asking for the public's help to contact Patti's friend "Becky", as she explains in the TikTok video below:

Police and Family Still Plead for Justice in Patti’s Case

Former Yakima Police Department detective, Noah Wentz, items that were taken from Patti's home were found about 50 yards away around the corner from where she lived. Wentz is stunned that this case has still not been solved and is asking the public for help.

"This is a situation that, it's 30 years ago, that's a time that I would like everybody to remember to see if they can't pry some memory loose of something they might have known or have seen back then." - Former YPD Detective Noah Wentz

Patricia's family is still "looking for answers, repercussions, and for justice."

"The person responsible for this heinous crime against an innocent person needs to have their life forever changed because their horrifying actions forever changed ours." - Patti's sister
