The Deputy Commander of the national Thai Royal Police, Lieutenant General Pansiri Prapawat, assumes control of the case tomorrow and security camera footage experts in Bangkok are already extracting clues.
Details have emerged from their examination of what the two men were wearing when they knifed the mother-of-three to death in the quiet beachside destination of Kata Noi at 10.30pm on Wednesday.
Police are hoping that the experts can eventually decipher from the grainy footage the number plate of the Honda Dream motorcycle the men were riding when they tried to snatch Mrs Smith's bag but fled empty-handed.
As well as the lieutenant general, a top policeman from the southern provinces headquarters, Colonel Pisan Jundilok, has been sent to Phuket to help form three separate task forces.
One group is looking at the getaway route, seeking more security camera footage, a second group is probing current suspects among known criminals, and the third is engaged with deciphering the security camera footage.
