Police are investigating after two women – a mother and her daughter – were found dead at a house in Southport.
Merseyside Police were called to the address in Fairhaven Road at around 5.45pm on Saturday where the bodies were discovered.
They have been named as Alice Huyton, 75, and 54-year-old Angela Holgate.
Officers are treating the deaths as unexplained. Post mortem examinations will take place next week to establish the cause.
Police are searching for lodger Barry Morrow
Detectives are keen to trace 51-year-old Barry Morrow who lived at the property and who they believe may have vital information.
He is described as white, 5ft 7in tall, of medium to stocky build with straight, short brown hair that is receding and blue eyes.
Mrs Huyton was last seen on Friday evening when she left her home in Southport to visit her daughter, who had been ill recently and had not been seen out of the house for some time.
Her husband, thought to be in his 80s, was said to be “devastated” at news of the deaths.
Mr Morrow, thought to be an engineer by profession, is understood to have links to France and Spain.
Ms Holgate’s white Citroen with the registration PN11 RWK is also missing.
Chief Superintendent Nikki Holland, area commander for Sefton, said: “We are investigating the tragic deaths of these two women and our sympathy goes to their families.
