British police have released bodycam footage showing a man in the United Kingdom drunkenly returning to the scene where he murdered a father of two.

Adrian Ellingford, 44, was stabbed multiple times at a residence in Chelmsford, Essex in July. Marek Hecko, 26, was found guilty of the murder on Monday and sentenced to life in prison, with a minimum of 26 years.

Essex Police bodycam footage shows Hecko approaching the scene on July 25 while drinking a bottle of brandy.

Hecko told officers that he knew "what happened" and that they could not investigate the murder without him.
