A YouTuber who faked a video game livestream to try to create an alibi while he fatally stabbed his pregnant girlfriend was sentenced to 31-years to life in prison after investigators exposed his scheme.

Northern Ireland gamer Stephen McCullagh, 36, was hit with the sentence on June 3 for stabbing his girlfriend Natalie McNally, 32, in the neck and strangling her at her home in Lurgan, in December 2022.

In an effort to stage an alibi, McCullagh set up a pre-recorded stream playing “Grand Theft Auto: Vice City” and “Robot Wars” for six hours on YouTube, according to the BBC.

McCullagh was found guilty of murder after a five-week trial earlier this year.

McNally was 15 weeks pregnant when McCullagh murdered her, according to police.
