The bodies of two people have been found inside a home.
Emergency services were called at about 9.30am on Tuesday to an address in Mersea Road, Colchester.
Inside the property, they found a woman, who had suffered injuries, and the body of a man.
Both were pronounced dead at the scene.
Essex Police have identified the pair as 41-year-old Kelly Greer and 34-year-old Jonathan Parsons, both from Colchester.
Specialist detectives and staff from the Kent and Essex Serious Crime Directorate are investigating and their enquiries are ongoing.
Detective Inspector James Holmes said: “My thoughts, and those of my team, are with the families and we are working hard to provide them with answers.
“We are making good progress with our investigation and are building a picture of the circumstances which led up to Kelly and Jonathan’s deaths.
“At this stage we do not believe anyone else was involved in the incident and we are not looking for anyone else in connection with it.
“However, we do still need the help of the public and I would urge anyone who has any information about the movements of Kelly and Jonathan, or if they saw or heard anything suspicious, in the days leading up to Tuesday to contact us.”
Anyone who has any information, CCTV, dash cam or other footage should contact Essex Police quoting crime reference number 42/97099/23.
