Benjamin Scott "horrific" stab attack at Sheffield flat
A detective who investigated the murder of a man stabbed more than 120 times has said it was "the worst case of violence" he has ever dealt with.
Gary Beech, 44, was murdered in June 2011 by Benjamin Scott, 32.
Det Ch Insp Zaf Ali, of South Yorkshire Police, said: "It was quite horrific. Many of the 120 wounds were to his head and eyes."
Scott was jailed indefinitely for public protection at Sheffield Crown Court on Tuesday.
He was originally charged with murder but a plea of manslaughter on the grounds of diminished responsibility was accepted.
Scott must serve a minimum of 15 years before he is considered for release.
Both men lived on Batemoor Road in Sheffield. The attack happened after the pair had been drinking at the victim's flat.
Mr Ali said: "The pathologist said many of [Mr Beech's] wounds were inflicted when the victim was incapacitated - down on the ground, possibly unconscious or even dead."
Police said Scott was diagnosed with a personality disorder and showed no remorse following the killing in June 2011.
After confessing to his girlfriend, the court heard that Scott agreed with her remark that the aftermath of the killing must have looked like a scene from the Saw horror films.
Mr Ali said Mr Beech was well liked, not violent in any way and quite small, at 5ft 2in tall.
He said the victim was dwarfed by 18-stone Scott, who was described by psychiatrists as "highly dangerous" and capable of "homicidal violence".
Scott was also convicted of wounding a prisoner following an attack in prison while he was on remand.
He attacked Daniel Clarke with a makeshift knife in Doncaster Prison, slashing his neck.
