Two teenagers have been sentenced for beating a man to death in a "revolting" attack while a 15-year-old girl filmed it on her mobile phone.
The judge said the pair "rejoiced in what they'd done"
Mark Masters, 19, of Parkwood Rise, Keighley, was sentenced to seven years in a young offenders' institution for killing Gavin Waterhouse.
Sean Thompson, 17, of Bradford, was ordered to serve six years for the 29-year-old's manslaughter.
The girl who recorded the attack will be sentenced on 18 March.
Thompson's address was given as Parkside Terrace, Cullingworth.
Leeds Crown Court heard Mr Waterhouse, who had a drink problem and was in bad health, had been drinking alone behind Morrisons supermarket in Keighley, when the pair attacked him on 23 September.
Masters asked the girl to film it in a so-called "happy slapping" and then repeatedly punched Mr Waterhouse in the face.
The court heard Thompson then pulled the victim to the ground where the pair took turns to kick him in the body.
Gavin was beaten "like a punch bag", the court heard
The trio ran off and bragged to friends about what they had done, while Mr Waterhouse died three days later, alone in his flat, from a ruptured spleen.
Judge James Stewart described the attack as "revolting, gratuitous and degrading".
Sentencing the pair, he added: "Each of you typifies the young, drunken, violent yob who hunt in packs of whom the public are sick and tired."
The court heard the three defendants showed others the "horrific" footage of the fatal beating to Mr Waterhouse, sent it to friends' mobile phones and even published it on the internet.
One witness who viewed the film said Masters lashed out at Mr Waterhouse "like a punch bag".
Judge Stewart added: "You rejoiced in what you had done, describing how you degraded and battered him."
A statement by the victim's mother, Christine Wiseman, said: "The fact that the attack on Gavin was also videoed makes me feel sick inside. I feel they devalued Gavin's life."
