Brizzi was found guilty of murder and sentenced by Judge Nicholas Hilliard QC to life with a minimum of 24 years, with seven years concurrent for disposing of the body.
The court heard that evidence from an odontologist settled the matter of whether Brizzi had in fact cannibalised part of his victim.
On examining a rib discarded in the kitchen bin, the expert found that a bite mark did in fact match the defendant's lower teeth.
Sentencing, Judge Hilliard said there were "terrible features" of the case and that Brizzi's drug addiction had ruined his life.
In the days after the killing, Brizzi was caught on CCTV buying buckets, a perforated metal sheet and cleaning products from a DIY store.
The court heard there was evidence in the kitchen that Brizzi had chopped up the Inverness-born officer with a variety of utensils and may have even used chopsticks to eat morsels of cooked meat.
Following his arrest, Brizzi admitted killing and trying to dissolve the body of the policeman because "Satan told me to".
The court heard that Brizzi had gone to Crystal Meth Anonymous meetings, but upset people by wearing a Breaking Bad T-shirt as the show "glorified" the drug.
