A woman found dead at home with her three children inside was the victim of a "sustained attack," an inquest has heard.
Rikki Lander, 26, was found in the living room of her home in Oldbury, West Midlands, on 5 August.
Her husband, Paul Lander, was also found dead in a different part of the house. He died as a result of hanging.
The couple's three young children had alerted neighbours that something was wrong.
Det Sgt Sue Hordern told the inquest it was clear Mrs Lander had undergone a "sustained attack" but that her cause of death was still not known.
Further tests will be carried out.
The body of Mr Lander, a 30-year-old HGV driver, was released to his family following the hearing.
Police have previously said they believe he killed his wife before killing himself.
A full inquest is set to take place on 16 October.
