According to reports, St. John never seemed to get over the death of his son, Julian, 24, who was found dead at La Casa Mental Health Hospital in Long Beach, CA., where he was seeking help in 2014.
Now it seems that his ex-wife Mia St. John, 51, believes that the same mental health unit is trying to kill her whole family and that she is being held against her will.
On February 7th, the WBC Boxing Champ posted a few messages on Twitter that have many people concerned.
Kristoff is also the father of daughters, Paris and Lola. He was soon to be married to fiancée Kseniya Mikhaleva.
Mia and St. John divorced in 1995 but remained friends and co-parents.
We hope that all is well and with Mia and her family and may Kristoff rest in peace.
