Kristina’s body was found on the evening of February 13.
Investigators determined she had been strangled before dying.
The verdict states the suspect confessed to strangling his wife.
An autopsy concluded that the body was then dismembered in the laundry room with a jigsaw, knife, and garden shears.
Body parts were then chopped up with a hand blender, ‘pureed’, and dissolved in a chemical solution, local outlet Blick reported.
A medical-forensic report also ‘contradicts his description of self-defence’, according to Swiss outlet FM1 Today.
Thomas, a Swiss national, was reportedly arrested a day after her remains were found.
Investigators have said Thomas, a businessman, displayed a ‘conspicuously high level of criminal energy’ in their assessment.
They cited a ‘lack of empathy and cold-bloodedness after killing his wife’, and his efforts to cover up her death, adding that the defendant exhibited ‘sadistic-sociopathic traits’.
The deceased won the Miss Northwest Switzerland pageant in 2003 and was a finalist in the 2008 Miss Switzerland competition.
