Murder for gain and murder with a gun both attract a 30 year minimum tariff, IIRC.
Murder with a bladed implement 25 years.
Whereas strangulation, unless there's evidence of a sadistic/sexual motive gets a lower tariff.
Two cases in my region. One involved a young man stabbing another young man. The other, a man choking his wife with chilli powder, strangling her and then making it look like a burglary.
Guess who got longer in prison?
