Murder in Nairn - student background of Alistair Wilson to be investigated

In the latest twist to the tragic doorstep murder of Alistair Wilson, which occurred very close to where I live last November, the police have now announced they are to check into the victim's earlier days, including his time as a student. Whether this is an indication that Northern Constabulary are still completely at a loss as to why this man was murdered, or whether they have definite reasons for going down this investigative route, who can tell? Further developments are awaited. My most recent previous article on the murder is here.
