Det Ch Insp Jon Hutchinson said the investigation was still "very active" and the force was determined to find the person responsible.
He added: "I would urge people to think back to this time a year ago, did a friend or loved one come home with blood on them or smelling of smoke?
"Were they acting strangely around that time? Did they suddenly come into money?
"Any information, no matter how small or insignificant it may seem, could prove crucial to solving this terrible crime and giving some closure to Mrs Crown's family who are desperate for answers."
