Two women found dead at a house in Oswestry, Shropshire, have been named locally as Susan McFall and her daughter Francesca.
The bodies of Susan and Francesca, who lived at the address with Mrs McFall's husband Hugh, were discovered shortly after 5am.
Later West Mercia Police said a man's body was found nearby. Police said the man's body, believed to be Mr McFall, was found at an industrial unit in St Martins, several miles from Oswestry.
Detective Inspector Mick Homden said: "I can confirm that officers discovered the body of a man at a location in the Oswestry area shortly after 9.30am. As a result, the police at this moment in time, are not looking for anyone else in connection with the deaths."
Craig Jones, a mechanic who works in the unit next door, said Mr McFall used the address as a base for his business, selling flowers to local supermarkets.
He said: "As I drove into work this morning at about 8.40am two police cars followed me in. I thought they were following me but they went next door.
"I think they kicked the door down, then they came round and told us we'd have to lock up. Now there are about four police cars here. I heard they found Hugh's body inside, and his truck is parked down the road. It's a shock because nothing ever happens in Oswestry."
Mr Jones said Mr McFall "kept himself to himself" and had been renting the unit for around a month.
Detective Superintendent Sheila Thornes, of West Mercia Police, said the house in Hampton Road remained cordoned off as more than 40 officers worked on the investigation.
A West Midlands Ambulance Service spokesman said: "We were called to the address just before 5.20am. After about an hour at the scene we were stood down by police."
A spokesman said: "A Home Office pathologist will conduct post mortems to establish the cause of death. The post mortem times have yet to be arranged."
Neighbours in Hampton Road described the McFalls as an "ordinary family" as they spoke of their shock at the murders.
One woman, who lives a few doors from their large detached home, said: "We had what you would call a nodding acquaintance, so I didn't know them terribly well but they were always friendly. They struck me as a nice ordinary family."
A West Mercia Police spokeswoman said the cause of death would be ascertained by a Home Office pathologist "in due course".
