The Record story is a bit of a dog's dinner. It says the man was "formally interviewed" but then talks of "a chat". It can't have been both. I've extracted a section from the story and highlighted what I think are the significant parts.
Cops investigating the murder of banker Alistair Wilson have formally interviewed a man in connection with the doorstep shooting.
The man, in his 50s, was questioned by detectives as a key witness in the case which has stumped police for 18 years.
The Daily Record understands the man, who is local to the area and whom we are not naming, was quizzed over his movements in the days before 30-year-old Alistair was gunned down at his front door in Nairn in the Highlands in 2004.
A senior police source said the man has been of interest to detectives for several years and, following new information, they took him in “for a chat.”
The source said: “There have been some things the squad has discovered that makes him of interest.
“He wasn’t interviewed at the time of the unsolved murder but his name has come up often in the new investigation.”
Certainly the tenor of the story suggests that the man, while not the man at the front door, is possibly somehow involved in the events leading up to the murder.
