The discovery of the body of a Met Police inspector found in woodland has been linked to the death of his mother-in-law Traute Maxfield.
Gary Weddell's body was found in woodland
Garry Weddell's body was found near Broomhill's Shooting Club, in Markyate, Herts, on Saturday morning.
Mrs Maxfield's body was found in Gustard Wood, Herts, also on Saturday.
Mr Weddell had been due to go on trial in May, for the murder of his wife, whose body was found in their home in Dunstable last year.
The body of Mrs Maxfield was found at a house in The Slype, Gustard Wood, on Saturday afternoon, 11 miles from the field where Mr Weddell was discovered.
Post-mortem examinations of both bodies are due take place on Monday morning, police said.
A forensic search of the gun club, of which Mr Weddell was a member until his licence was revoked following his arrest, is under way.
Det Supt Andy Shrives, of Herts Police, said: "We are keen to trace the movements of Mr Weddell on Friday and Saturday.
"I am also keen to speak to anyone who may have attended Broomhill's Shooting Club on these days."

Officers also want to speak to anyone who saw Mr Weddell's car, a metallic green Renault Laguna with the registration NY53ONT.
Mr Weddell was originally held in custody after being charged with the murder of his 44-year-old wife, Sandra.
A post-mortem examination revealed that a cable tie was used to strangle her.
He was later granted bail with a surety of £200,000 by Judge John Bevan at Ipswich Crown Court.
Mike Penning, Conservative MP for Hemel Hempstead, said he was going to write to the Attorney General to ask why Mr Weddell had been freed on bail.
Mr Penning said: "If you are on a charge of murder, that sounds like you are a risk.
"There are so many questions we need to know now as to why this gentleman was not in custody when he was facing such serious charges."
