Doing a piece on a 10 year-old that killed his father, but twenty-eight years later, he couldn't remember that he actually killed his own father. I was wondering if Electroconvulsive therapy (ECT) or Electro-shock treatment could have been performed on him at that time to make him forget. Also, could there have been other options to make someone forget that they committed such a crime? I am open to ideas. The character is a full blown killer now and couldn't remember that he'd killed before. Any suggestions? Thanks.
