Earlsfield, London, December 9 2008

Victim:

Andrew Cunningham.

The 52-year-old convicted paedophile (pictured above) was stabbed in the chest, throat and head in his caravan, outside the haulage yard where he worked.

The killer also mutilated Cunningham`s genitals, fuelling speculation that his murder was connected to a conviction for unlawful sex with a 15-year-old girl in 2001.
