Photo issued by Linconshire Police of Lucas Markham and Kim Edwards, believed to be Britain's youngest double murderers, who can now be named as the two 15 year olds who were convicted of murdering Edwards' mother and sister in Spalding.

The pair, both 15, were convicted of murdering Edwards’ mother and sister in Spalding last April.

Markham and Edwards were both aged 14 at the time of the murders, had sex, shared a bath and watched vampire-themed films after the murders of dinner lady Elizabeth Edwards, 49, and 13-year-old Katie Edwards.

Now both 15, the couple were handed minimum terms of 20 years last November by Mr Justice Haddon-Cave, who said the pair had a “toxic” relationship and had acted in a grotesque way after the stabbings in Spalding.

Q Where did you think up to kill your family, to do it via a knife, to stab them in the throat, to have a bath afterwards, to commit suicide afterwards? Where’s all this come from? Where’s all this, have you seen something like it, have you read something like it?

A Well no not really I just erm went with general knowledge really er well cos the voice box and the stabbing in the throat and the bath cos of the dog er so she wouldn’t smell the (unintelligible) Lucas I don’t like the smell of blood erm and just yeah and committing suicide after it’s just most people who do commit murders try to commit suicide themselves just most people do....

Q ....well it’s alright, some people have yeah but, it’s...so that’s your idea behind it alright erm so there was nothing that you’d seen, you’d read or anything that gave you this sort of notion nobody had discussed it with you
