Stephan Dietrich will be facing a judicial pre trial on May 11th, in regards to the First Degree Murder of his wife Mimi in 2015. Dietrich made an appearance at the Ontario Superior Court of Justice yesterday where they set the date. Mimi disappeared in 2014, with people believing she returned to her home country of Ethiopia for charity work. It wasn’t until her abandoned vehicle was discovered in front of her Wyndham Street Business that the situation became suspicious. Eleven months later her remains were found on her family’s Vancouver Drive Property on the east end of Guelph.
