5. Richard Dyson
Richard, from Hoyland, Barnsley, was last seen, by his daughter in November 2019.
Detectives investigating his disappearance have made arrests on suspicion of his murder as part of the investigation – despite no body being found. Nobody has been charged.
South Yorkshire Police have previously said: "Despite officers pursuing many lines of enquiry, Richard has not been traced and evidence that has recently been reviewed now suggests he may have been killed, despite no body being found."
Detective Inspector Neil Coop said: "Since Richard disappeared my team and I have worked tirelessly to understand the circumstances surrounding this case.
"Unfortunately, we have not yet been able to trace him and sadly now believe he may have been killed.
"This investigation is progressing quickly, and I once again appeal to anyone who has information that may help to come forward. It’s not too late."
