A woman apparently murdered by her husband who then committed suicide had suffered neck injuries, an inquest has heard.
Barry Harrison, 47, and his wife Amanda, 34, were found inside the property in Regal Court, High Street, Shanklin, Isle of Wight, on Monday.
The inquest at Newport Coroner's Court heard that the couple's two sons, aged three and five, were found in the flat by a friend of the family.
Coroner's officer Richard Leedham said the friend went round to the flat after a family member raised concerns having not been able to contact them.
The elder son opened the door and told her that both parents were sleeping. She then found Mr Harrison hanging from a rope in a bedroom with his wife dead on the floor in the same room.
Mr Leedham said Mrs Harrison had suffered neck injuries.
The inquest heard that a post-mortem examination carried out by Home Office pathologist Dr Russell Delaney gave a cause of death of hanging for Mr Harrison.
But the examination carried out on Mrs Harrison was inconclusive with further laboratory tests set to be carried out to establish a "direct" cause of death, the hearing was told.
Assistant deputy coroner for the Isle of Wight Hugh Calloway adjourned the inquest to a date to be set.
Hampshire and Isle of Wight police said they are treating Mrs Harrison's death as "suspicious" and Mr Harrison's as "non-suspicious". They are not seeking anyone else in connection with the deaths.
