Scenes-of-crime officers examined the scene
Police have named a 21-year-old man they want to speak to after the bodies of a woman and her baby daughter were discovered in Hampshire.
Officers want to talk to Anthony Marsh after the bodies of Stephanie Bellinger, 24, and 10-month-old Lily were found at house near Southampton.
Police were called to Myrtle Avenue, Totton, on Saturday morning after the pair were found by a relative.
A police spokesman said Mr Marsh was a "murder suspect" and a "dangerous" man.
Detectives want to speak to Mr Marsh as a "matter of urgency", he added.
'Do not approach'
"Mr Marsh has had no contact with family or friends since the bodies were discovered by a relative just before 9am," he said.
He has gone missing before, visiting cities including Brighton and Plymouth, but his whereabouts remain unknown.
Known to travel by rail, the suspect either sleeps rough or in churches, police said.
"Mr Marsh is dangerous and should not be approached," the spokesman added.
"If anyone has seen him or someone matching his description they should not approach him but phone the police immediately by dialling 999."
Mr Marsh is white, 6ft 2in tall, with short fair hair, brown eyes, of slim build and has a tattoo on his left forearm.
Hampshire Police are appealing for anyone in the area of Myrtle Avenue to contact them.
Post-mortem examinations on the bodies were likely to be conducted by a Home Office pathologist either later or on Sunday morning.
Anyone with information is being asked to contact the investigation team at the major crime suite in Hulse Road, Southampton.
