A horrified neighbour found the bodies of a married couple at their seaside flat after hearing their two young sons screaming.
The woman went to investigate and, finding the front door open, walked in to discover their father hanging from a ceiling rafter and his wife dead in a bedroom.
It is believed the mother had been strangled by her husband before he killed himself last night.
The two traumatised boys, both under the age of five, were tearful and running around the apartment.
The couple have not been named but are in their 30s. They had lived in the £150,000 flat in the seaside resort of Shanklin on the Isle of Wight for a year.
Their two children were today being looked after by a family friend.
Mr Isted said: ‘A neighbour heard shouting and a rumpus coming from the flat and went upstairs because she was concerned.
‘The noise was their two young children screaming and crying because they were so traumatised.
‘The front door was ajar so she walked in and directly in front of her she could see the husband’s legs dangling in the front room. He'd apparently hanged himself.
'She then went into the next room, the bedroom, where the door was also ajar and she saw the wife's legs. She was lying dead on the bed.
'The two young children were running around screaming obviously traumatised by what they had seen and she called the police.
Detectives from Hampshire Constabulary's Major Crime Department and Isle of Wight CID are today seeking to contact next-of-kin so the bodies can be formally identified.
Post mortem examinations are due to be carried out today.
