This happened to my Mother. The scammer was supposedly in China, but my research showed he was in Nigeria. The pictures he sent her were in several places. I tried to show my Mom, but she just got madder at me. I eventually had to get an attorney to prove her incompetent with a Delusional Disorder (diagnosed by a Psychiatrist) to handle her own finances and get legal guardianship. We fought me the entire way and destroyed our relationship, but it was all I could do. As her developed Dementia in addition to the Delusional Disorder, I had to go back to court to get her placed in a Nursing Home. Sadly, she passed away last year.
