The slowest murderer I've ever heard about,lebaleb. Most are keen to get it over and done with without extra fuss and palava like getting ready for the part ( wet-suit ),making sure the tyres are pumped up because of using a bicycle. He'd have to have left the basket on it for his change of clothing after the bloodbath.
Sorry about this next quip,but two barking dogs would have wakened the dead,let alone surrounding neighbours in their cottages. So they'd have been silenced first.
He sure did waste an awful lot of time considering all the" arranging" he made after the massacre. It's a miracle nobody came knocking at the sound of the dogs barking.
If all this seems too good to be true---------that's because it is !!
