Moment man pulls out a knife and stabs a father to death

A doorbell camera captured the horrific moment a man pulled out a knife and stabbed a father to death. Kane Kotwica, 39, fatally stabbed his neighbour Matthew Cainey, 53, and wounded two others in a block of flats on May 28 this year. The chilling footage from a neighbouring flat showed the moments leading up to the murder. It shows Kotwica taking a knife out of his hoody pocket and stabbing Mr Cainey in his chest as he stood in the hallway of his flat on in Gloucester.
