John Blackburn jailed for murdering sister's boyfriend
A man has been jailed for life for murdering his sister's boyfriend during a row at a party in County Durham.
Cole Wilson, 20, suffered stab wounds to the head and chest at the house in Sledmere Close, Peterlee, on 18 September 2011.
John Blackburn had denied murder but was found guilty by a jury at Newcastle Crown Court in February.
The 20-year-old, of Holywell Avenue, Walker, was sentenced to life, with a minimum term of 17 years.
A Durham Police spokesman said: "John Blackburn was responsible for a violent attack on a young man who died as a result of multiple stabs wounds.
"The sentence he has received should serve as a warning to others that if they resort to violence, particularly using knives, they will suffer the consequences."
