Michael Hewerdine: Murder detectives begin excavation in 20-year cold case
Detectives have begun a dig in a field as part of an investigation into the murder of a man who disappeared 20 years ago.
Michael Hewerdine, 32, from Ruskington, Lincolnshire, went missing on 21 November 1996 after leaving his home to meet people in nearby Sleaford.
Police said prior to his disappearance he had told friends he was extremely concerned for his safety.
Lincolnshire Police are excavating a field in East Heckington.
A murder investigation began in 1999 following a case review by police.
Detectives said they are carrying out the excavation near the A17 between Swineshead Bridge and Sleaford after receiving new information.
Det Ch Insp Martin Holvey, of the East Midlands Major Crime Unit, said: "As part of our enquires we have identified new witnesses and leads."
The force said the dig is expected to last between one and two weeks.
Mr Hewerdine was born and brought up in Ruskington and most of his friends knew him as Hewey.
Michael's sister, Madeleine Judd, said the family needed closure.
"My brother Mick has been missing for 20 years," she said.
"His mother, myself and his daughter - we all really need to know what has happened to him, so if you have any information whatsoever, please contact the police."
