The bodies of two women have been found at a house in Leamington Spa.
Warwickshire Police said it forced entry at a home on Binswood Street at 14:00 BST on Monday after "concern was raised for the occupants".
Post mortem examinations and formal identification are due to take place on the women, who are believed to have been aged 38 and 55 and in a couple.
Det Insp Liam Barry said police are not looking for anyone else in connection with the "tragic incident".
The force said the incident is thought to have been "contained to the property" and asked for privacy for both families.
