A gold chain worn by Sheffield murder victim Simon Holdsworth is missing, detectives have revealed.
A mobile phone used by the 36-year-old family man has also not been found.
Officers investigating Mr Holdsworth’s brutal murder on December 16 believe he would have had both items on him at the time of his death.
Temporary Det Supt Phil Etheridge, who is leading the investigation, said: “We have been carrying out extensive and detailed enquiries in the weeks since Mr Holdsworth’s body was found.
“He was known to wear a gold chain and use a black Nokia 201 phone and would have had these items on him the night he died.
“We are keeping an open mind as to how the phone and chain came to be missing and would appeal to anyone who believes they have seen either item, or knows where they are, to call police immediately.”
The body of Mr Holdsworth, of Westfield Avenue, Hackenthorpe, was found by a member of the public in a field off Birley Spa Lane at 6.30am on December 17.
He used to play football and go sledging with his son, who turned four on Christmas Eve, on the same field.
On December 16, Mr Holdsworth finished work at FBS Prestige in Intake, where he worked as a paint sprayer, at 10.55pm.
A colleague gave him a lift to a bus stop on Mansfield Road and he got on the number 120 First Bus shortly after 11pm.
CCTV footage has shown Mr Holdsworth getting off at his usual stop, in Birley Spa Lane, about 10 minutes later but he never made it home that night.
His body was found the following morning and a post mortem revealed he had died of multiple, severe head injuries caused by a ‘blunt’ weapon.
Temporary Det Supt Etheridge said: “I would also like to take this opportunity to reiterate my appeal for anyone who saw Simon after he got off the 120 bus at around 11.10pm on the night before his body was found. I would also urge people to call police if they saw someone acting suspiciously in the Delves Road area, close to the Hogs Head Public House, around this time.
“Additionally I would like to hear from anyone else who knows the whereabouts of the missing items.”
