A 63-year-old man has been arrested on suspicion of murder following the grim discovery in the village of Ugley in Essex on Tuesday evening.
Cops were called to Cambridge Road around 9.50pm following reports of two people being seriously injured.
When officers attended they found a woman in her 50s and a man in his 20s injured.
Sadly, they were pronounced dead at the scene.
The man arrested is from Ugley and remains in custody.
Detective Inspector Lydia George said: “My thoughts are with the loved ones of the two people who were killed in Ugley last night. This will be an unimaginably difficult time for them and they will be supported by specialist officers.
“I know this incident will cause concern among within the local community but I want to reassure them that we have a team of experienced detectives and staff investigating.
“At this stage we do not believe this incident poses a risk to the wider public and we’re not looking for anyone else in connection with it.”
Anyone with information should call 101 and quote incident 1271 of May 28.
