well,drugs ..
If both of these young people were addicts ,
nope, in reading this over and over and seeing that the area is not a good area,
I think they were just a regular couple that were trying to make ends meet in a bad
neighborhood, theres alot of stories similar, there was another couple found and
two young children found alone and the parents were dead, and another polish
lorry driver in same area, town.
I dont doubt that who ever did this might have wanted money from them for drugs
but I dont think it was them.
The area itself is a bad area, and this story screams homicide.
