Police carried out a reconstruction exercise in a Rotherham town overnight as part of the hunt for the killer of a former soldier.
Tommy Ward was brutally attacked and left for dead in a robbery at his home in Maltby on October 1, 2015.
The 80-year-old, from Salisbury Road, suffered a smashed skull, broken ribs and fractured jaw in the attack and died four months later.
A safe, containing Mr Ward's £30,000 life savings, was stolen in the raid.
Arrests have been made but nobody has been charged over the killing.
Last night, detectives investigating the death carried out a reconstruction exercise, in which a number of roads in the town were closed.
Residents received letters warning them that the exercise would be carried out between 10pm yesterday and 3am, today.
Parts of Salisbury Road, Grange Lane, Highfield Park, Churchill Avenue and Manor Road were closed for the exercise.
Residents were asked not to have vehicles or skips parked on the roads.
They were also asked to keep their curtains and blinds drawn.
A South Yorkshire Police spokeswoman said: "A reconstruction exercise took place in Maltby overnight on Sunday, June 11, in connection to the Tommy Ward murder investigation.
"The exercise, which solely relates to previously released CCTV footage of vehicular movement, will now be analysed."
Anyone with information about the murder should call South Yorkshire Police on 101 or Crimestoppers on 0800 555111.
