'Mystery' over A47 double death in Norfolk

The reasons why two people died on a dual carriageway in Norfolk are still a "mystery", a senior detective has said.

A man and woman, who were Lithuanian and in their 20s, were killed on the A47 near Terrington St John on Sunday.

Officers are treating the woman's death as suspicious, believing she may have been pushed into oncoming traffic.

Det Ch Insp Paul Durham said: "I'm quite satisfied I know how physically they have met their deaths, but what I really don't understand is what's led to that."
