Details of disappearance and psychic work by Brian Ladd (login to view entire case as of May 2020)


Kantonen was last seen at Arnold Aggas Sr.'s residence in Hornbrook, California on March 8, 1989. She was carrying a black purse at the time of her disappearance. She has never been heard from again.
Kantonen was dating Aggas's son at the time of her disappearance, and they lived together in a trailer on Aggas's property. Her boyfriend was involved with someone else, however, and had invited the other woman to share the trailer. Kantonen had to sleep on the couch and was very unhappy about it. The last time she saw her mother, said said her boyfriend's father had a bad temper and had made unwanted sexual advances. After Aggas found out Kantonen was pregnant, he was reportedly angry and prevented her from seeking prenatal care. Her mother tried to convince her to move out, but Kantonen wanted to marry Aggas's son.

In June 2011, Aggas was arrested for sex crimes committed in 2007. When the authorities searched his residence, they found unspecified evidence that lead them to charge him with murdering Kantonen. A photo of Aggas is posted below this case summary. In April 2014, he pleaded no contest to two counts of involuntary manslaughter (one count for Kantonen and one for her unborn child). He was sentenced to thirteen years in prison; with credit for time served, he will be released in eight years.
Foul play is suspected in Kantonen's case due to the circumstances involved.
