Cash was withdrawn using the victim's card at a NatWest machine in Stamford
Police investigating the murder of a Lincolnshire man will use bluetooth to send new images of a suspect to mobile phone users.
Alan Wood, 50, was found stabbed to death at his home in Lound, on 24 October.
Cash was withdrawn using the victim's card at a NatWest machine in Stamford on Saturday and Sunday.
The new images were taken from CCTV footage from a mobile phone shop in Stamford.
Police released an E-fit of the suspect last week
The image is being sent to mobile phones in the Stamford and Bourne areas this weekend.
Det Supt Stuart Morrison said: "We want people to study these fresh images and look at them in the context of the previous CCTV footage we have released and the E-fit.
"These pictures are much better quality and give you an idea of exactly what the suspect was wearing.
"If you recognise this man at all then please contact us. "
Mr Wood, who was last seen on 21 October, has been described as a placid person who "wouldn't hurt a fly".
He worked as a gardener and at the nearby Sainsbury's supermarket.
