Woman who killed boyfriend over 'trust issues' sentenced to six years' prison

A Christchurch woman who assaulted and strangled her boyfriend to death because she believed he was spreading rumours about her has been sentenced to six years and three months in prison.

Zariah Samson, 25, will serve a minimum non-parole term of three years and three months after pleading guilty to manslaughter in a deal with the Crown to downgrade her initial charge of murder.

She was sentenced at the Christchurch High Court on Friday.

The victim, Cory Protos, who was 30 years old at the time, died on April, 26, 2014.

Mr Protos went to pick up some personal property from Samson's address before heading to another address where he met up with Samson.

There, she became angry and accused him of spreading rumours about her.

At that address, Mr Protos was made to take off all of his clothing to prove he wasn't wearing any recording devices.

He was then assaulted and bound by his hands and covered with a blanket where Samson punched and kicked him.

Later that night Mr Protos went with Samson to another address in Christchurch where he showered before the argument continued.

It was then Samson caused a superficial cut to his neck and wrapped a cable around his neck and strangled him.

She then wrapped him in a blanket and pushed him under a bed.
