Have They Considered Doing These Tests On The Judge?

Psychiatric tests found the man was 'normal' mentally and fully aware of what he was doing.

And what was he doing?

Eating his mother. Which, according to the judge, was no biggie:

The Russian criminal code dictates 15 years in jail for his crimes but the judge said he was reducing it slightly because Gavrilov - who previously served time in jail for robbery - pleaded guilty and 'he was not keen to eat the meat, he just was hungry'.

Mmmm, so Russia has 'yummy mummies' just like here, only....different...
